Peter Collingbourne 235c275b20 IR, X86: Understand !absolute_symbol metadata on global variables. 
Summary:
Attaching !absolute_symbol to a global variable does two things:
1) Marks it as an absolute symbol reference.
2) Specifies the value range of that symbol's address.
Teach the X86 backend to allow absolute symbols to appear in place of
immediates by extending the relocImm and mov64imm32 matchers. Start using
relocImm in more places where it is legal.

As previously proposed on llvm-dev:

Differential Revision: https://reviews.llvm.org/D25878
