Fix llvm-symbolizer test broken by #199739 (#199801)
I broke this test in #199739. As a result to that change, the start of
the CODE section in the linked WASM file shifted from 0x41 to 0x37 (a
shift of -10 bytes).
I was not aware that `wasm-ld` had testing outside of `lld/test/wasm`.
[RISCV][NFC] Remove SegInstSEW for unused function (#199598)
Since SegInstSEW is only used by segment load/store, no need to keep it
for other builtins.
[RISCV][P-ext] Add DefVXSAT argument to tablegen classes. NFC (#199797)
Sink the lets Defs = [VXSAT] into the classs.
This makes the encoding based structure of this file more consistent.
[lit] Add --fn to prepend llvm-extract for function-level test narrowing
Add a --fn=name1,name2 flag to llvm-lit that prepends
llvm-extract --func=<name> to the first pipeline stage of each
RUN line whose first stage references %s. This lets users narrow
IR tests to specific functions and their dependencies without
modifying test files.
[BOLT][NFC] Split out function marking from profile parsing
Move out `setHasProfileAvailable` into `markFunctionsWithProfile`.
This also allows extracting per-pre-aggregated type handling in
`parseAggregatedLBREntry` into a switch statement.
Test Plan:
NFC
Processing time change (wall time):
* 10MB pre-aggregated profile:
- Parsing aggregated branch events: 0.16s -> 0.05s
- Pre-process profile data (parsing+marking): 0.18s -> 0.16s
* 6GB perf.data file:
- Parsing branch events: 29.06s -> 28.55s
- Pre-process profile data (excluding perf script): 29.47s -> 29.13s

[LLD][COFF] Gate second-dot section-name stripping on MinGW (#199625)
The comment in getOutputSectionName has always called the second-dot
stripping "for MinGW" (e.g. .ctors.NNNN), but the code applied it on
every target. This hiddes a split-dwarf bug #199616.
Take an isMinGW gate and skip the stripping when it is false.
[llvm-mca] Fix total execution count in Average Wait times (#199500)
Fix the column `0` for the `<total>` row in llvm-mca's `Average Wait times` report. The `total`
row now represents the total dynamic execution count used to normalize the averages,
instead of the per-instruction iteration count. Update the timeline view docs and autogenerated
test expectations accordingly.
