*	[CodeGen] fix const-ness of builtin equivalents of <math.h> and <complex.h> ↵	Sanjay Patel	2017-11-02	1	-4/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	functions that might set errno This just makes const-ness of the builtins match const-ness of their lib function siblings. We're deferring fixing some of these that are obviously wrong to follow-up patches. Hopefully, the bugs are visible in the new test file (added at rL317220). As the description in Builtins.def says: "e = const, but only when -fmath-errno=0". This is step 2 of N to fix builtins and math calls as discussed in D39204.

*	[CodeGen] map sqrt libcalls to llvm.sqrt when errno is not set	Sanjay Patel	2017-10-31	1	-0/+19
	The LLVM sqrt intrinsic definition changed with: D28797 ...so we don't have to use any relaxed FP settings other than errno handling. This patch sidesteps a question raised in PR27435: https://bugs.llvm.org/show_bug.cgi?id=27435 Is a programmer using __builtin_sqrt() invoking the compiler's intrinsic definition of sqrt or the mathlib definition of sqrt? But we have an answer now: the builtin should match the behavior of the libm function including errno handling.
