[DAGCombiner] Fix invalid size request in combineRepeatedFPDivisors
If we have a vector FP division with a splatted divisor, use

For AArch64 the combine kicks in for the <vscale x 4 x float> case since it's
above the fdiv threshold (3) when scaling num uses by splat factor, but the

If the combine could be converted into a scalar FP division by

while the symbol created via an alias had the type set to

This matches what GCC does, which emits directives for setting the
COFF symbol type for this kind of alias symbol too.
This makes a difference when GNU ld.bfd exports symbols without
dllexport directives or a def file - it seems to decide between
function or data exports based on the COFF symbol type. This means
that functions created via aliases, like some C++ constructors,
are exported as data symbols (missing the thunk for calling without
dllimport).
The hasnt been an issue when doing the same with LLD, as LLD decides

[LLVM][AIX] Prefer a 32-bit default target triple on AIX
If the user doesn't specify a default target triple, the LLVM CMake usually defaults us into the host triple. This is a problem when building Clang/LLVM on 64-bit AIX (i.e. powerpc64-ibm-aix), as the host toolchain (e.g. ar, ld, nm, dump) all expect the compiler to generate 32-bit objects by default (which both GCC and XL on the platform do) and will hard error if passed a 64-bit object without an explicit option or environment setting. This breaks downstream consumers, such as builds generated with build tools like CMake, which when they invoke clang, etc. without explicit bitmode flags also expect 32-bit mode.
This patch changes the default target selection when the host is powerpc64-ibm-aix to prefer powerpc-ibm-aix to avoid these issues. We don't update the runtimes/CMakeList.txt since the default is less meaningful as we assume runtimes will need to build for both targets anyways.

[WebAssembly] Nullify unnecessary setjmp invokes
This is similar to D116619, but now it handles `invoke`s. The reason we
didn't handle `invoke`s back then was we didn't support Wasm EH + Wasm
SjLj together, and the only case SjLj transformation will see `invoke`s
is when we are using Wasm EH. (In Emscripten EH, they would have been
transformed to `call`s to invoke wrappers.)
But after D117610 we support Wasm EH + Wasm SjLj together and we can
nullify `invoke`s to `setjmp` when there is no other longjmpable calls
within the function. Actually this is very unlikely to happen in
practice, because we treat destructors as longjmpable and also treat
`__cxa_end_catch` as longjmpable even if it is not.

[WebAssembly] Handle cleanuppad with no parent in Wasm SjLj
Wasm SjLj converts longjmpable calls into `invoke`s that unwind to
`%catch.longjmp.dispatch` BB, from where we check if the thrown
exception is a `longjmp`. But in case a call already has a `funclet`
attribute, i.e., it is within a catch scope, we have to unwind to its
unwind destination first to preserve the scoping structure. That will
eventually unwind to `%catch.longjmp.dispatch`, because all
`catchswitch` and `cleanupret` that unwind to caller are redirected to
`%catch.dispatch.longjmp` during Wasm SjLj transformation.
But the prevous code assumed `cleanuppad`'s parent pad was always an
instruction, and didn't handle when a `cleanuppad`'s parent is `none`.
This CL handles this case, and makes the `while` loop more intuitive by
removing `FromPad` condition and explicitly inserting `break`s.
