This patch fixes builtins' CMakeLists.txt and their VFP tests to check the standard macro defined in the ACLE for VFP support. It also enables the tests to be built and run for single-precision-only targets while builtins were built with double-precision support. Differential revision: https://reviews.llvm.org/D92497
