Paul Kirth 6047deb7c2 [llvm] Provide utility function for MD_prof ...

Currently, there is significant code duplication for dealing with
MD_prof metadata throughout the compiler. These utility functions can
improve code reuse and simplify boilerplate code when dealing with
profiling metadata, such as branch weights. The inent is to provide a
uniform set of APIs that allow common tasks, such as identifying
specific types of MD_prof metadata and extracting branch weights.

Future patches can build on this initial implementation and clean up the
different implementations across the compiler.
