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.
