e41149a7ec * x86_64: reworked register saving/restoring to use PUSH/POP instructions for procedures with RSP-based frame and SEH finalization procedures. XMM registers are also saved/restored without involving tempgen in mentioned cases. This prevents SEH finalization procedures from saving registers in stack frame of their parent procedures, fixing incorrect unwind bytecode (Mantis #24791). It also reduces executable size (for compiler itself, by about 100Kb).

fcaad5baf2 * perform -CTlowercaseprocstart conversion it tprocsym.create rather than 
when building the mangled name, because the latter can also be performed
    when compiler another unit (and therefore if that other unit's setting
    is different from that of the original unit, a wrong mangled name was
    generated) + test for this case

5dda96bdfe - Tcgx86_64.init_register_allocators: removed 'preserved_by_proc' parameter, because it isn't used by RA in any way.

ff95d42216 Fix ShiftShift2Shift 1 ARM-peephole optimizer 
The previous code deleted the newly inserted instruction instead of the
existing one, which obviously broke code.

Assembly:
  mov r0, r0, lsr #23
  mov r0, r0, lsr #23

transformed into:
  mov r0, r0, lsr #23

expected was:
  mov r0, #0

The problem only shows up in the very unlikely case of two LSR/ASR or
two LSL following on each other and having a total shift of more than 31
bits.

This fixes test/opt/tarmshift.pp

I've also removed the {%norun} directive from tarmshift.pp as this test
does only make sense when it also runs.

b81f746e05 Inline Length(DynamicArray) 
Up until now a helperfunction was called at runtime. This change inlines
the whole code in the same way Length(AnsiString) works. As dynamic
arrays do not record their length but their highest index, an additional
"OP_ADD" is this case.
