Fixes #55794, introduced by #55558.

I have decided to go with this fix (see discussion in #55794 (comment)) for now because:

  1. RC1 and the other fixes are more disturbing;
  2. fix during morph:fgInitArgInfo looks like:
ASG(LCL_VAR double temp, originalArg)
LCL_FLD long temp
CALL

and it causes the argument to be read from memory when before it could stay in float registers.
3. it is dangerous to do morph arg changes when we don't have actual armel testing.
