We need to set up a proper framework for handling warnings and errors.

There are a few places in InstrBuilder where we call llvm::report_fatal_error.
This will become a problem when we decide to finalize bug 37696 and we move
towards llvm-mca as a library.
We don't want to have calls to report_fatal_error from inside of the library
code. Instead, errors and warnings should be correctly diagnosed outside of
InstrBuilder.

This is a blocker for bug 37696.
