 - 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.

Add a simplified EmitJumpThroughFinally and use it in CGObjC in preparation of making it use the cleanup stack.

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.

Add support for emitting cleanup blocks. Make EmitCompoundStatement emit cleanup blocks if necessary

llvm-svn: 64051

Add a simple RAII object, to be used for pushing a cleanup entry and make the insertion point be the cleanup block.

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.

 - Lift CGFunctionInfo creation above ReturnTypeUsesSret and
   EmitFunction{Epi,Pro}log.

llvm-svn: 63553

 - Lift CGFunctionInfo creation up to callers of EmitCall.

 - Move isVariadic bit out of CGFunctionInfo, take as argument to
   GetFunctionType instead.

No functionality change.
