  [SLP]Better decision making on whether to try stores packs for vectorization

Since the stores are sorted by distance, comparing the indices in the
original array and early exit, if the index is less than the index of
the last store, not always the best strategy. Better to remove such
stores explicitly to try better to check for the vectorization
opportunity.

Fixes #115008

  [RISCV] Match single source deinterleave shuffles for vnsrl (#114878)

We had previously only been matching the two source case where both
sources came from a wider source type. We can also match the single
source case - provided the result is m4 or smaller because we will need
a wider type to represent the source.

The main goal of this to ensure that vnsrl matching is robust to a
possible change in canonicalization for length changing shuffles that
I'm considering, but it has the nice effect of picking up a few cases we
missed along the way.

  [memprof] Add extractCallsFromIR (#115218)

This patch adds extractCallsFromIR, a function to extract calls from
the IR, which will be used to undrift call site locations in the
MemProf profile.

In a nutshell, the MemProf undrifting works as follows:

- Extract call site locations from the IR.
- Extract call site locations from the MemProf profile.
- Undrift the call site locations with longestCommonSequence.

This patch implements the first bullet point above.  Specifically,
given the IR, the new function returns a map from caller GUIDs to
lists of corresponding call sites.  For example:

Given:

  foo() {
    f1();
    f2(); f3();
  }

extractCallsFromIR returns:

  Caller: foo ->
    {{(Line 1, Column 3), Callee: f1},
     {(Line 2, Column 3), Callee: f2},
     {(Line 2, Column 9), Callee: f3}}

where the line numbers, relative to the beginning of the caller, and
column numbers are sorted in the ascending order.  The value side of
the map -- the list of call sites -- can be directly passed to
longestCommonSequence.

To facilitate the review process, I've only implemented basic features
in extractCallsFromIR in this patch.

- The new function extracts calls from the LLVM "call" instructions
  only.  It does not look into the inline stack.
- It does not recognize or treat heap allocation functions in any
  special way.

I will address these missing features in subsequent patches.

  [clang][serialization] Pass `ASTContext` explicitly (#115235)

This patch removes `ASTWriter::Context` and starts passing `ASTContext
&` explicitly to functions that actually need it. This is a
non-functional change with the end-goal of being able to write
lightweight PCM files with no `ASTContext` at all.
