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.

Daniel Neilson 2574d7cbf6 All libcalls should be considered to be GC-leaf functions. 
Summary:
It is possible for some passes to materialize a call to a libcall (ex: ldexp, exp2, etc),
but these passes will not mark the call as a gc-leaf-function. All libcalls are
actually gc-leaf-functions, so we change llvm::callsGCLeafFunction() to tell us that
available libcalls are equivalent to gc-leaf-function calls.
