Commit 49599cb1a20cc4f4d6d2f71965f2069ae8d4f96a by esme.yi [PowerPC] Correct the bit-width definition for some imm operand in td. Summary: The imm operands of some instructions are not defined accurately in td. This is a small patch to correct these definitions.

Commit deac8b1f450ff7d2d00218d962c3e7e5ff1ff86e by aeubanks [test] Fix widen-iv.ll under NPM The -loop-flatten legacy pass preserves loop analyses. The legacy PM will check all passes that preserve loop analyses that they preserve LCSSA. This implicitly involves running -loop-simplify. The test shouldn't depend on verify flags being set in order to run -loop-simplify, so explicitly add it. The new PM ends up not running it otherwise.

Commit 6e614b0c7ed3a9a66428f342bf2a4b3700525395 by Vitaly Buka [NFC][MSan] Round up OffsetPtr in PoisonMembers getFieldOffset(layoutStartOffset) is expected to point to the first trivial field or the one which follows non-trivial. So it must be byte aligned already. However this is not obvious without assumptions about callers. This patch will avoid the need in such assumptions. Depends on D92727.
