[RISCV] transform MI to W variant to remove sext.w

Backwards search
The sext.w removal pass (before the new patch) checks if the input to sext.w is already in sign-extended form, so it can eliminate it. It does that by checking every definition/source that reaches the sext.w is an instruction that produces a sign-extended value, either by definition (e.g. ADDW), or it propagates sign-extension (e.g. OR) so we check its sources recursively.

Forward search
Sometimes, one of the sources is an instruction that doesn't always produce a sign-extended value, but it has a W-version that does (e.g. ADD / ADDW). If we transform the ADD to ADDW, the sext.w can be removed (assuming other def paths are satisfied), but this transformation is sound only if every use of this ADD/W only reqruires the lower 32-bits either directly (like sll %x, 32) or they propagate dependency (lower word of output only depends on lower word of input) so we check its uses recursively.

When searching backwards, if an instruction that can be replaced with W-variant is encountered, this pass runs the forward search to verify it can be replaced, then adds it to a list of fixable instructions. After verifying all paths, it replaces the instruction and removes the sext.w.

GlobalISel: Relax handling of G_ASSERT_* with source register classes

copy from a physical register, which happens to use set the actual
register class on the virtual register. After copy coalescing, the
assert's source operand had a vreg with a set class. The verifier was
strictly rejecting cases where the set class/bank weren't an exact
match. Additionally, RegBankSelect was also expecting a register bank
to be set on the register, not a class.

This is much stricter than regular copies so relax this behavior. This
now allows these 2 cases:

1. Source register has either class or bank, and the result does not
2. Source register has a register class, and the result is a register
with a matching bank.

[flang] Make the plugin API independent of the driver internals

This patch adds a few new member methods in the `PluginParseTreeAction`
frontend action base class. With these new methods, the plugin API
becomes independent of the driver internals. In particular, plugin
writers no longer require the `CompilerInstance.h` header file to access
various driver data structures (instead, they can use newly added
hooks).

This change is desirable as `CompilerInstance.h` includes various
headers from Clang (both explicitly and implicitly). Some of these
header files are generated at build time (through TableGen) and
including them creates a dependency on some of Clang's build targets.
However, plugins in Flang should not depend on Clang build targets.

Note that plugins might still work fine most of the time, even without
this change and without adding Clang build targets as dependency in
plugin's CMake definition. Indeed, these Clang build targets are often
generated early in the build process. However, that's not guaranteed and
