Summary:
This makes clang-format sort using declarations case-sensitive with the
exception that '_' comes just before 'A'. This is better than the current case
insensitive version, because it groups uppercase names in the same namespace
together.

When a preamble ends in a conditional preprocessor block that is being
skipped, the preprocessor needs to continue skipping that block when
the preamble is used.

This fixes PR34570.

Summary:
CUDA doesn't support errno at all, so this is the right thing -- or at
least, in the right direction.

But also, this unbreaks the CUDA test-suite math tests [0] after D39481.
__cuda_cmath.h forwards nexttoward() to __builtin_nexttoward, which,
after that patch, was lowering to a libcall that doesn't exist in NVPTX.

Since they'll likely (not always - if the address is taken, etc) be
inlined away, even at -O0, separately provided weak definitions are
likely to be unused so skip all of that.

Consistent with various workarounds in the backwards compatible modules
that allow static functions in headers to exist, be deduplicated to some
degree, and not generally fail right out of the gate... do the same with
modular codegen as there are enough cases (including in libstdc++ and in
LLVM itself - though I cleaned up the easy ones) that it's worth
supporting as a migration/backcompat step.

Simply create a separate, internal linkage function in each object that
needs it. If an available_externally/modularized function references a
static function, but the modularized function is eventually dropped and
not inlined, the static function will be dropped as unreferenced.

[CodeGen] fix const-ness of builtin equivalents of <math.h> and <complex.h> functions that might set errno

This just makes const-ness of the builtins match const-ness of their lib function siblings. 
We're deferring fixing some of these that are obviously wrong to follow-up patches. 
Hopefully, the bugs are visible in the new test file (added at rL317220).

As the description in Builtins.def says: "e = const, but only when -fmath-errno=0".

This is step 2 of N to fix builtins and math calls as discussed in D39204.

Given a choice between a constructor call and a conversion function in C++17,
we prefer the constructor for direct-initialization and the conversion function
for copy-initialization, matching the behavior in C++14 and before. The
guaranteed copy elision rules were not intended to change the meaning of such
code (other than by removing unnecessary copy constructor calls).

This tweak will be raised with CWG.
