Tim Northover fcb00d4aec Reapply: LLVM IR: update Clang tests for byval being a typed attribute. 
Since byval is now a typed attribute it gets sorted slightly differently by
LLVM when the order of attributes is being canonicalized. This updates the few
Clang tests that depend on the old order.

Clang patch is unchanged.

Tim Northover 4b281755ae Revert "LLVM IR: update Clang tests for byval being a typed attribute." 
The underlying LLVM change couldn't cope with llvm-link and broke LTO builds.

Eric Fiselier b42c73de3d Fix PCC test failures for source location builtins

Eric Fiselier 708afb56c1 Implement __builtin_LINE() et. al. to support source location capture. 
Summary:
This patch implements the source location builtins `__builtin_LINE(), `__builtin_FUNCTION()`, `__builtin_FILE()` and `__builtin_COLUMN()`. These builtins are needed to implement [`std::experimental::source_location`](https://rawgit.com/cplusplus/fundamentals-ts/v2/main.html#reflection.src_loc.creation).

With the exception of `__builtin_COLUMN`, GCC also implements these builtins, and Clangs behavior is intended to match as closely as possible.
