The strictfp metadata was added to the casting AST nodes in D85960 <https://reviews.llvm.org/D85960>, but we aren't using that metadata yet. This patch adds that support.

In order to avoid lots of ad-hoc passing around of the strictfp bits I updated the IRBuilder when moving from a function that has the Expr* to a function that lacks it. I believe we should switch to this pattern to keep the strictfp support from being overly invasive.

For the purpose of testing that we're picking up the right metadata, I also made my tests use a pragma to make the AST's strictfp metadata not match the global strictfp metadata. This exposes issues that we need to deal with in subsequent patches, and I believe this is the right method for most all of our clang strictfp tests.
