TargetLibraryInfo: Use pointer index size to determine getSizeTSize(). (#118747)

When using non-integral pointer types, such as on CHERI targets, size_t

pointer.

Related issue: https://github.com/llvm/llvm-project/issues/113711

Note: It's my first time contributing to the LLVM with encouragement
from one of my friends, @fawdlstty. I learned a lot from
https://github.com/llvm/llvm-project/pull/99611, and thanks for that.

Note: I had created the same PR and merged
(https://github.com/llvm/llvm-project/pull/113724), but reverted caused
by the merging issue. (The CI issue happened in 3 A.M. at my timezone.
So, I need to fall asleep again after I replied about why issue
happened.) So, I rebased to the latest main branch and recreate the PR
and hope I won't have the third time to create the same PR.

I hope @arsenm can help me review the code again. I’m sorry for that.

Enhance TLI detection of __size_returning_new lib funcs. (#102391)

Previously the return types of __size_returning_new variants were not
validated based on their members. This patch checks the members
manually, also generalizes the size_t checks to be based on the module
instead of being hardcoded.

TargetLibraryInfo: Assume no libcalls in the default constructor (#92400)

The only tricky point here is PlaceSafepoints has an awful hack where
it's creating a legacy PassManager inside it's runImpl, which was not
propagating the incoming TLI. This means there's an implicit bug fix,
where PlaceSafepoints would have been treating too many calls as
builtins.

I'm trying to delete the default constructor altogether, but this seems
to be more difficult.

[NFC][TLI] Move VecFuncs to statics to reduce stack usage (#86829)

`TargetLibraryInfoImpl::addVectorizableFunctionsFromVecLib` has a lot of
data in local stack arrays, which MSVC keeps on the stack even in
release builds. To reduce stack usage, the data arrays (which are
const), are moved outside the function as statics. This drops the method
stack usage to be negligible.

[Analysis] Treat ldexpf() as missing on MinGW (#84748)

The function does exist, but it is a plain wrapper over regular ldexp(),
so there's no benefit in calling it over regular ldexp(). Therefore,
treat it as missing.

This fixes builds of Wine for aarch64 with Clang in mingw mode, which
regressed recently in 8d976c7f20fe8d92fe6f54af411594e15fac25ae. That
commit unlocked transforming calls to ldexp into ldexpf, for some
codepaths within Wine. Wine can use compilers in mingw mode without
the regular mingw runtime libraries, which caused this to fail.
(However, if the transformation to use ldexpf() would have made sense,
the right fix would have been for Wine to provide a similar
ldexpf->ldexp wrapper just like mingw does.)
