Revert "Revert "[X86] Remove patterns for ADC/SBB with immediate 8 and optimize during MC lowering, NFCI""

2023-05-19T14:21:56+00:00

This reverts commit cb16b33a03aff70b2499c3452f2f817f3f92d20d.

In fact, the test https://bugs.chromium.org/p/chromium/issues/detail?id=1446973#c2
already passed after 5586bc539acb26cb94e461438de01a5080513401

This caused compiler assertions, see comment on
https://reviews.llvm.org/D150107.

This also reverts the dependent follow-up change:

> This is follow-up of D150107.

[X86] Remove patterns for ADD/AND/OR/SUB/XOR/CMP with immediate 8 and optimize during MC lowering, NFCI

2023-05-19T10:22:30+00:00

This is follow-up of D150107.

In addition, the function `X86::optimizeToFixedRegisterOrShortImmediateForm` can be
shared with project bolt and eliminates the code in X86InstrRelaxTables.cpp.
