Add an escape-hatch for conversion of funcs with blocking awaits to coroutines.

Currently TFRT does not support top-level coroutines, so this functionality will allow to have a single blocking await at the top level until TFRT implements the necessary functionality.

Handle subregs and superregs in callee-saved register mask

If a target lists both a subreg and a superreg in a callee-saved
register mask, the prolog will spill both aliasing registers. Instead,
don't spill the subreg if a superreg is being spilled. This case is hit by the
PowerPC SPE code, as well as a modified RISC-V backend for CHERI I maintain out
of tree.

[clang][patch][FPEnv] Make initialization of C++ globals strictfp aware

@kpn pointed out that the global variable initialization functions didn't
have the "strictfp" metadata set correctly, and @rjmccall said that there
was buggy code in SetFPModel and StartFunction, this patch is to solve
those problems. When Sema creates a FunctionDecl, it sets the
FunctionDeclBits.UsesFPIntrin to "true" if the lexical FP settings
(i.e. a combination of command line options and #pragma float_control
settings) correspond to ConstrainedFP mode. That bit is used when CodeGen
starts codegen for a llvm function, and it translates into the
"strictfp" function attribute. See

Support macro deprecation #pragma clang deprecated

This patch adds `#pragma clang deprecated` to enable deprecation of
preprocessor macros.

The macro must be defined before `#pragma clang deprecated`. When
deprecating a macro a custom message may be optionally provided.

Warnings are emitted at the use site of a deprecated macro, and can be
controlled via the `-Wdeprecated` warning group.

This patch takes some rough inspiration and a few lines of code from
