  Revert "[SLP]Attempt to vectorize long stores, if short one failed."

This reverts commit 6f7160eedb2db02f37d4ffd52fff7b0cf88b3fdc.

This still causes large compile-time regressions in some cases.

  [InstCombine] Fix poison propagation in round up alignment fold

We can't directly use the high bits value if it is more poisonous
due to poison elements in the masks.

This fixes the issue reported in

  [clang-format] Revert breaking stream operators to previous default (#89016)

Reverts commit d68826dfbd98, which changes the previous default behavior
of always breaking before a stream insertion operator `<<` if both
operands are string literals.

Also reverts the related commits 27f547968cce and bf05be5b87fc.

See the discussion in #88483.
