[lldb][NFCI] Remove use of ConstString from UnixSignals::SignalCode

On llvm.org and all downstream forks that I'm aware of, SignalCodes are
always created from C string literals. They are never compared to
anything so they take up space in the ConstString StringPool for no
tangible benefit.

I've changed the type here to `const llvm::StringLiteral` instead of
using a `StringRef` or a `const char *` to express intent -- These
strings come from constant data whose lifetime is directly tied to that
of the running process (and are thus safe to store).

Revert "[ARM] Allow D-reg copies to use VMOVD with fpregs64"

This reverts commit 0a762ec1b09d96734a3462f8792a5574d089b24d.

Some CPUs enable fp64 by default (such as cortex-m7). When specifying a
single-precision fpu with them like -mfpu=fpv5-sp-d16, the fp64 feature will
be disabled, but fpreg64 will not. We need to disable them both correctly under
clang in order for the backend to be able to use the reliably. In the meantime
this reverts 0a762ec1b09d96734 until that issue is fixed.

[Lex] Only warn on defining or undefining language-defined builtins

D144654 made it so that we warn on any defining or undefining of
builtin macros. However the C and C++ standards only forbid the
defining or undefining of macros defined in the language standard
itself, but clang defines more macros than those and warning on those
may not be helpful.

Resolve this by only warning if the builtin macro name is the name of
a macro defined by the language. This is done in a way that removes
some of the existing checks, as those were made redundant by
restricting the warning in this way.

Alexandros Lamprineas [Thu, 1 Jun 2023 14:09:08 +0000 (15:09 +0100)]
[IPSCCP] Decouple queries for function analysis results.

The SCCPSolver is using a structure (AnalysisResultsForFn) where it keeps
pointers to various analyses needed by the IPSCCP pass. These analyses are
requested all at the same time, which can become problematic in some cases.
For example one could be retrieved via getCachedAnalysis() prior to the
actual execution of the analysis. In more detail:

The IPSCCP pass uses a DomTreeUpdater to preserve the PostDominatorTree
in case the PostDominatorTreeAnalysis had run before IPSCCP. Starting with
commit 1b1232047e83b the IPSCCP pass may use BlockFrequencyAnalysis for
some functions in the module. As a result, the PostDominatorTreeAnalysis
may not run until the BlockFrequencyAnalysis has run, since the latter
analysis depends on the former. Currently, we setup the DomTreeUpdater
using getCachedAnalysis to retrieve a PostDominatorTree. This happens
before BlockFrequencyAnalysis has run, therefore the cached analysis can
become invalid by the time we use it.
