cdbb5e336d Set call attribute for direct calls (i.e. noreturn). 
- Remove an unused variant of EmitCallExpr overload.

8eb018ab9c Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow. 
- Define pow[lf]?, sqrt[lf]? as builtins.

 - Add -fmath-errno option which binds to LangOptions.MathErrno

 - Add new builtin flag Builtin::Context::isConstWithoutErrno for
   functions which can be marked as const if errno isn't respected for
   math functions. Sema automatically marks these functions as const
   when they are defined, if MathErrno=0.

 - IRgen uses const attribute on sqrt and pow library functions to
   decide if it can use the llvm intrinsic.

284d177c7f Wire up break and continue processing to the new stack depth adjuster. 
If people could beat on it and let me know if there are any new
semantics required by newer language standards or DRs or any little
details I goofed on, I'd be happy to fix any issues found.

0509d9635b Ensure we track all the stack depths for all break and continue points 
correctly.  This should lay the ground work to throw the big switch
and start code gening break and continue in the presense of vlas.

Specify external linkage for such globals so that llvm optimizer do
not assume there values initialized as zero.

0196a1cd2b This patch fixes the code gen failures which was a fallout from 
not merging protocol properties into the classes which
use those protocols. With this patch, all my exceutable
test pass again.

8a01b79274 Change EmitVLASize to take a QualType that must be a variably modified type. 
Emit the size even if the declared type is a variably modified type. This lets us handle

void f(int n) {
  int (*a)[n];
  
  printf("size: %d\n", sizeof(*a));
}
