Alyssa Rosenzweig	384882744c	DeadStoreElimination: drop now that it's redundant ... it's only really load bearing for pf/af, which is handled as a global flag opt now. this mitigates some of the compile time hit from globalizing flag opts.

Alyssa Rosenzweig	b36d1f7e7b	RedundantFlagCalculationElimination: optimize parity ... another global CFG-based optimization -- if we know that the raw PF is already 1-bit we can skip parity evaluation, saving work with floating point compares.

Billy Laws	f7b911ca43	OpcodeDispatcher: Do not forbid INT 2E syscalls on 64-bit Windows ... This works fine on real Windows and is relied on by wine as SystemCall is set to 1 in KUSER_SHARED_DATA, which causes the ntdll thunks to use it over `syscall`	2024-09-06 15:58:17 +00:00

Alyssa Rosenzweig	d1d4d2d876	ConstProp: stop pooling inline constants ... Because we already pooled the _Constants, there's no benefit to also pooling inline constants. the robin map to do so just adds extra overhead for no benefit - drop it. without multiblock, shaves around 2% off node. with multiblock, a bit less than 1% but still a win.
