Currently the *tf builtin functions can only be built if long double is an IEEE float, which prevents them from being available e.g. for x86 targets (unlike libgcc which has them). This non-functional change prepares the builtins library *tf functions for being able to target x86 by decoupling their presence from CRT_LDBL_128BIT and instead checking for a CRT_HAS_TF_MODE macro. This change is NFC since the CRT_HAS_TF_MODE is currently only set if long double is an IEEE 128-bit float. Reviewed By: compnerd Differential Revision: https://reviews.llvm.org/D153812
