Vlad Tsyrklevich 57076d3199 Revert "Change the X86 datalayout to add three address spaces for 32 bit signed," 
This reverts commit r370083 because it caused check-lld failures on

Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass."" 
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Eric Christopher a863435128 Temporarily Revert "Add basic loop fusion pass." 
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Rong Xu a5b5745a62 [PGO] Fix PGO use ICE when there are unreachable BBs 
For -O0 there might be unreachable BBs, which breaks the assumption that all the
BBs have an auxiliary data structure.  In this patch, we add another interface
called findBBInfo() so that a nullptr can be returned for the unreachable BBs
(and the callers can ignore those BBs).

This fixes the bug reported
