We hit the following assert when doing full AOT of some assemblies: wrong maximal instruction length of instruction localloc (expected 96, got 99) Assertion: should not be reached at mono\mono\mini\mini-amd64.c:6801 Turns out that that size could be hit when a couple of things happens as part of lowering OP_LOCALLOC and OP_LOCALLOC_IMM: sreg1 is not RAX, RCX or RDI dreg is not RAX, RCX or RDI cfg->param_area is bigger than 127 Fix is to increase max size of the instruction, from 96 -> 120 (same as x86).

We hit the following assert when doing full AOT of some assemblies:
wrong maximal instruction length of instruction localloc (expected 96, got 99)
Assertion: should not be reached at mono\mono\mini\mini-amd64.c:6801
Turns out that that size could be hit when a couple of things happens as part of lowering OP_LOCALLOC and OP_LOCALLOC_IMM:
sreg1 is not RAX, RCX or RDI
dreg is not RAX, RCX or RDI
cfg->param_area is bigger than 127
Fix is to increase max size of the instruction, from 96 -> 120 (same as x86).
