I think these intrinsics were added after the Commutative was added to most of the rest of the intrinsics and it must have been forgotten.

All these records are internalized and will live until exit. This makes
them perfect candidates for a fast BumpPtrAllocator.

This avoid an extra construction of a std::string (and a heap

hand.

The variable was assigned to, but never used. The functions called did not

This was accidentallly broken in r285515 when we started lowering the intrinsic to an ISD node. Should fix PR31241.

Previously this pass was using up to 5% compile time in some cases which
is a bit much for what it is doing. The pass featured a full blown
data-flow analysis which in the default configuration was restricted to a
single block.
This rewrites the pass under the assumption that we only ever work on a
single block. This is done in a single pass maintaining a state machine
per general purpose register to catch LOH patterns.

VSX has instructions lxsiwax/lxsdx that can load 32/64 bit value into VSX register cheaply. That patch makes it known to memory cost model, so the vectorization of the test case in pr30990 is beneficial.

Summary:
This is a follow up to r288303, where I have introduced TrigramIndex
to speed up SpecialCaseList for the cases when all rules are
simple wildcards, like *hello*wor.d*.
Here, I add support for escaping, so that it's possible to
specify rules like *c\+\+abi*.

This resubmits r288529, which was resubmitted because it broke a
fuzzer bot. According to kcc@ the test that broke was flakey
and it is unlikely to be a result of this patch.

Windows doesn't really support weak aliases, but with some
linker magic we can get something that's pretty close on
Windows. This introduces an interface to accessing weakly
aliased symbols that will work on any platform. Linker
magic changes to come in a separate patch.

For -O0 there might be unreachable BBs, which breaks the assumption that all the
BBs have an auxiliary data structure. In this patch, we add another interface
called findBBInfo() so that a nullptr can be returned for the unreachable BBs
(and the callers can ignore those BBs).
This fixes the bug reported

Add assembler support for all atomic instructions that weren't already

atomic operations, but this isn't done here yet.
