This commit was reverted in 30e7ee3c4bac <https://reviews.llvm.org/rG30e7ee3c4bac4a12ea584a879aa320bd4e035cc2> because a null deref error occurred in IRBuilder.h when setting strictfp attribute, see https://bugs.llvm.org/show_bug.cgi?id=44048 for information about that bug.
This patch moves setting strictfp from IRBuilder into clang/CodeGen. Also addresses some code review comments that were received after the revert.  I'll add some inline comments next.
