[RISCV] Combine ADDD with UMUL_LOHI/SMUL_LOHI into WMACCU/WMACC (#180383)

Combine the pattern:
  ADDD(addlo, addhi, UMUL_LOHI(x, y).0, UMUL_LOHI(x, y).1)
into:
  WMACCU(x, y, addlo, addhi)

And similarly for SMUL_LOHI -> WMACC.


This patch was written with AI, but I reviewed it carefully.

[RISCV] Emit MULHU/MULHS/UMUL_LOHI/SMUL_LOHI from our custom XLen*2 expansion. (#180379)

We already do all the checks necessary in order to prioritize
MULHU/MULHS/UMUL_LOHI/SMUL_LOHI over MULHSU/WMULSU. We might as
well just emit the nodes instead of letting generic type legalization
redo the checks.

This is slightly different than the default legalization because we
don't have access to ExpandInteger so we have to emit TRUNCATES and
BUILD_PAIR. Not sure if this will result in any differences in practice.

[Docs][Intrisics] Fix the name of llvm.memset.inline in the documentation (#180373)

LLVM intrinsic `llvm.memset.inline` indicates in its name the types of
the destination pointer and the size. There is no second pointer.

Moreover, the tests are already verifying that generated code uses
`@llvm.memset.inline.p0.i32` and `@llvm.memset.inline.p0.i64`. So make
the documentation reference these names as well.

There are some cases where it is non-trivial to get access to a

helper to create a MDNode for unknown branch weights if the function is
profiled to handle this case.
