* Mark libc math shims with always_inline attribute We want these to always be inlined, so mark them with ... always_inline. The compiler happened to do the right thing with them previously, but we shouldn't depend on that. <rdar://problem/30043258> master-next: IRGen/builtin_math.swift failing because sqrt(4) is not constant folded
