Expand PerfMap format to support metadata for symbol indexation (dotn…
e3dd985 
…et#53792)

I have expanded the PerfMap format produced by Crossgen2 and
R2RDump to produce metadata in form of pseudo-symbol records with
high addresses. In this version I have implemented four metadata
entries - output GUID, target OS, target architecture and perfmap
format version number.  I have verified for System.Private.CoreLib
and for the composite framework that Crossgen2 and R2RDump
produce identical metadata.

To facilitate a smooth transition to the new perfmap format, in
accordance with Juan's suggestion I have introduced a new command-line
option to explicitly specify the perfmap format revision. As of today,
0 corresponds to the legacy Crossgen1-style output where the
perfmap file name includes the {MVID} section, perfmap format #1
corresponds to current Crossgen2 with its new naming scheme.
As of today there are no differences in the file content.

Thanks

Tomas

Fix native frame unwind in syscall on arm64 for VS4Mac crash report. (d…
dc67c70 
…otnet#63598)

* Fix native frame unwind in syscall on arm64 for VS4Mac crash report.

Add arm64 version of StepWithCompactNoEncoding for syscall leaf node wrappers that have compact encoding of 0.

Fix ReadCompactEncodingRegister so it actually decrements the addr.

Change StepWithCompactEncodingArm64 to match what MacOS libunwind does for framed and frameless stepping.

arm64 can have frames with the same SP (but different IPs). Increment SP for this condition so createdump's unwind
loop doesn't break out on the "SP not increasing" check and the frames are added to the thread frame list in the
correct order.

Add getting the unwind info for tail called functions like this:

The IP (367bc) returns the (incorrect) frameless encoding with nothing on the stack (uses an incorrect LR to unwind). To fix this
get the unwind info for PC -1 which points to PROCEndProcess with the correct unwind info. This matches how lldb unwinds this frame.

Always address module segment to IP lookup list instead of checking the module regions.

Fix the MacOS remote unwinder for VS4Mac (dotnet#63405)
3c2d2a1 
* Fix the MacOS remote unwinder for VS4Mac

The wrong module was being passed to the remote unwinder because the load bias for shared modules
was being calculated incorrectly.

Issue: dotnet#63309

* Fix native frame unwind in syscall on arm64 for VS4Mac crash report

From PR in main: dotnet#63598

Add arm64 version of StepWithCompactNoEncoding for syscall leaf node wrappers that have compact encoding of 0.

Fix ReadCompactEncodingRegister so it actually decrements the addr.

Change StepWithCompactEncodingArm64 to match what MacOS libunwind does for framed and frameless stepping.

arm64 can have frames with the same SP (but different IPs). Increment SP for this condition so createdump's unwind
loop doesn't break out on the "SP not increasing" check and the frames are added to the thread frame list in the
correct order.

Add getting the unwind info for tail called functions like this:

__ZL14PROCEndProcessPvji:
   36630:       f6 57 bd a9     stp     x22, x21, [sp, #-48]!
   36634:       f4 4f 01 a9     stp     x20, x19, [sp, dotnet#16]
   36638:       fd 7b 02 a9     stp     x29, x30, [sp, dotnet#32]
   3663c:       fd 83 00 91     add     x29, sp, dotnet#32
...
   367ac:       e9 01 80 52     mov     w9, dotnet#15
   367b0:       7f 3e 02 71     cmp     w19, dotnet#143
   367b4:       20 01 88 1a     csel    w0, w9, w8, eq

Add arm64 support for EnC (dotnet#69679)
8ca9916 
This adds support for EnC on arm64. A couple of notes on the
implementation compared to x64:
- On x64 we get the fixed stack size from unwind info. However, for the
  frames we set up on arm64 for EnC it is not possible to extract the
  frame size from there because their prologs generally look like

  stp fp, lr, [sp,#-16]!
  mov fp, sp
  sub sp, sp, dotnet#144

  with unwind codes like the following:

  set_fp; mov fp, sp

  save_fplr_x #1 (0x01); tp fp, lr, [sp, #-16]!

  As can be seen, it is not possible to get the fixed stack size from
  unwind info in this case. Instead we pass it through the GC info that
  already has a section for EnC data.

- On arm64 the JIT is required to place the PSPSym at the same offset
  from caller-SP for both the main function and for funclets. Due to
  this we try to allocate the PSPSym as early as possible in the main
  function and we must take some care in funclets.  However, this
  conflicts with the EnC frame header that the JIT uses to place values
  that must be preserved on EnC transitions. This is currently
  callee-saved registers and the MonitorAcquired boolean.

  Before this change we were allocating PSPSym above (before) the
  monitor acquired boolean, but we now have to allocate MonitorAcquired
  first, particularly because the size of the preserved header cannot
  change on EnC transitions, while the PSPSym can disappear or appear.
  This changes frame allocation slightly for synchronized functions.

Improve DisplayNameHelpers for NativeAOT (dotnet#70084)
1b4a9c4 
These helpers are used to report names of things in warnings. The functional changes are:
* For method parameters, use the parameter name if available (and only if not fallback to the #1 notation)
* For property accessor methods, use the C# naming scheme, so for example Type.Property.get instead of Type.get_Property.

Both of these changes are in preparation to bring NativeAOT closer in behavior to ILLink and the trim analyzers.

For this I moved some of the helpers to the common shared code.

Some unrelated code cleanup as well.

Improve LSRA and other dump output
7802740 
E.g.,

Update LSRA "Allocating Registers" table description.

Dump nodes added during resolution, e.g.:
```
   BB29 bottom (BB08->BB08): move V25 from STK to rdi (Critical)
N001 (  1,  1) [001174] ----------z                 t1174 =    LCL_VAR   int    V25 cse4          rdi REG rdi
```

Dump more data in the LSRA block sequence data:
```
-BB03( 16   )
-BB04(  4   )
+BB03 ( 16   ) critical-in critical-out
+BB04 (  4   ) critical-out
```

When dumping various flow bitvectors, annotate the bitvectors better:
```
-BB25 in gen out
-0000000000000000
-0000000000000003 CSE #1.c
-0000000000000003 CSE #1.c
+BB25
+ in: 0000000000000000
+gen: 0000000000000003 CSE #1.c
+out: 0000000000000003 CSE #1.c
```

Dump hoisting bitvectors using the sorting number:
```
-  USEDEF  (5)={V04 V00 V01 V02 V03}
+  USEDEF  (5)={V00 V01 V02 V03 V04}
```

Also, fix various typos and formatting.

The JitDump is unfinished because the compiler crashes when trying to dump the last line. Clearly, the `CNS_INT` is no longer a handle at that point because we just bashed it to a constant 1.
