Alp Toker d3d017cf00 Reduce verbiage of lit.local.cfg files 
We can just split targets_to_build in one place and make it immutable.

Daniel Dunbar 9efbedfd35 [tests] Cleanup initialization of test suffixes. 
- Instead of setting the suffixes in a bunch of places, just set one master
   list in the top-level config. We now only modify the suffix list in a few
   suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py).

 - Aside from removing the need for a bunch of lit.local.cfg files, this enables
   4 tests that were inadvertently being skipped (one in
   Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and
   CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been
   XFAILED).

 - This commit also fixes a bunch of config files to use config.root instead of
   older copy-pasted code.

Shuxin Yang c5c730b0e0 PR14904: Segmentation fault running pass 'Recognize loop idioms' 
The root cause is mistakenly taking for granted that 
    "dyn_cast<Instruction>(a-Value)"
return a non-NULL instruction.

David Tweed a11edf0ce3 There was a switch fall-through in the parser for textual LLVM that caused 
bogus comparison operands to default to eq/oeq. Fix that, fix a couple of
tests that accidentally passed and test for bogus comparison opeartors
explicitly.

Chandler Carruth 91e47532fe Revert the patches adding a popcount loop idiom recognition pass. 
There are still bugs in this pass, as well as other issues that are
being worked on, but the bugs are crashers that occur pretty easily in
the wild. Test cases have been sent to the original commit's review
thread.

This reverts the commits:
  r169671: Fix a logic error.
  r169604: Move the popcnt tests to an X86 subdirectory.
  r168931: Initial commit adding the pass.

David Tweed cfeb8fc49a The test unconditionally assumes a particular cpu has a backend build in the target. 
Buildbots for some hosts may choose to build only their own backend in order to
maximise testing-turnaround time. Move the test into a prefixed directory so
lit's standard "backend specific" suppression can be done.
