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.

Xinliang David Li 4cdc9dab0a Renable r314928
Eliminate inttype phi with inttoptr/ptrtoint.

 This version fixed a bug in finding the matching
 phi -- the order of the incoming blocks may be 
 different (triggered in self build on Windows).
 A new test case is added.

Reid Kleckner b6b210e61f Revert "Roll forward r314928"
This appears to be miscompiling Clang, as shown on two Windows bootstrap
bots:
http://lab.llvm.org:8011/builders/clang-x86-windows-msvc2015/builds/7611
http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/builds/6870

Nothing else is in the blame list. Both emit errors on this valid code
in the Windows ucrt headers:

C:\...\ucrt\malloc.h:95:32: error: invalid operands to binary expression ('char *' and 'int')
            _Ptr = (char*)_Ptr + _ALLOCA_S_MARKER_SIZE;
                   ~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~

I am attempting to reproduce this now.

This reverts r315044

Fixed ThinLTO bootstrap failure : track new
bitcast per incomingVal. Added new tests.

Xinliang David Li 7a73757358 Recommit r314561 after fixing msan build failure
(trial 2) Incoming val defined by terminator instruction which
also requires bitcasts can not be handled.

Daniel Jasper 3c9c60c727 Revert r314579: "Recommi r314561 after fixing over-debug assertion".
And follow-up r314585.
Leads to segfaults. I'll forward reproduction instructions to the patch
author.

Also, for a recommit, still add the original patch description.
Otherwise, it becomes really tedious to find out what a patch actually
does. The fact that it is a recommit with a fix is somewhat secondary.

Xinliang David Li 5b9d96825b Eliminate PHI (int typed) which has only one use by intptr
This patch will eliminate redundant intptr/ptrtoint that pessimizes
analyses such as SCEV, AA and will make optimization passes such
as auto-vectorization more powerful.
