Eli Bendersky b198b4e864 Rename loop unrolling and loop vectorizer metadata to have a common prefix. 
[Clang part]

These patches rename the loop unrolling and loop vectorizer metadata
such that they have a common 'llvm.loop.' prefix.  Metadata name
changes:

llvm.vectorizer.* => llvm.loop.vectorizer.*
llvm.loopunroll.* => llvm.loop.unroll.*

This was a suggestion from an earlier review
(http://reviews.llvm.org/D4090) which added the loop unrolling
metadata. 

Patch by Mark Heffernan.

Alexander Musman 515ad8c490 This patch adds a helper class (CGLoopInfo) for marking memory instructions with llvm.mem.parallel_loop_access metadata. 
It also adds a simple initial version of codegen for pragma omp simd (it will change in the future to support all the clauses).
