  [RISCV][NFC] Remove direct access to FeatureKV (#206233)

This is preparatory work for changing the representation of
FeatureKV/SubTypeKV, in which they will no longer be that easily
accessible as global variables. Therefore, get them from the subtarget
instead.

  [InstCombine] Optimize fcmp ord/uno logical select operations using freeze (#205076)

This pull request optimizes logical select sequences checking ordered or
unordered floating point operations.

Currently, InstCombine canonicalizes:

fcmp ord x, 0.0 AND fcmp ord y, 0.0 to fcmp ord x, y
fcmp uno x, 0.0 OR fcmp uno y, 0.0 to fcmp uno x, y
However, this canonicalization is blocked for logical selects because it
is not poison safe if the second operand evaluates to poison when the
first evaluates to NaN.

This patch enables the transformation for logical selects by inserting a
freeze on the second evaluated operand to guarantee poison safety.

Fixes #49175

  Reland: [NFC][Support] Implement slash-agnostic path matching in GlobPattern (#206251)

Add a SlashAgnostic option to GlobPattern to allow matching path
separators
(both forward slashes and backslashes) agnostically.

When enabled:
- We conservatively reduce the plain prefix and suffix by treating path
  separators as metacharacters. This ensures that path separators are
  matched via the slash-agnostic state machine rather than plain string
  comparison.
- Brackets containing slashes are adjusted to match both separators.
- Character comparisons in the state machine (matchChar) treat '/' and
  '\' as equivalent.

For #149886.

Reland of #202854 incorrectly reverted in #205409.
