- Remove unneeded FIRST concept in loop table; it was always equal to TOP. - Rename optMarkLoopsBlocks to optScaleLoopBlocks to more accurately describe what it does. More consistently report block scaling in the dump - Create optMarkLoopHeads. This was refactored out of fgRemoveUnreachableBlocks so it can be called in a more logical location (at the beginning of optFindLoops), and only does one thing. - fgMakeOutgoingStructArgCopy: remove unused `argIndex` argument; reorder calls to fgMightHaveLoop. - Update and write a bunch of comments; convert away from `/* */` style comments.
