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.

Craig Topper 69f8c1653d [ScalarizeMaskedMemIntrin] Use IRBuilder functions that take uint32_t/uint64_t for getelementptr, extractelement, and insertelement. 
This saves needing to call getInt32 ourselves. Making the code a little shorter.

The test changes are because insert/extract use getInt64 internally. Shouldn't be a functional issue.

This cleanup because I plan to write similar code for expandload/compressstore.

Craig Topper 6911bfe263 [ScalarizeMaskedMemIntrin] When expanding masked gathers, start with the passthru vector and insert the new load results into it. 
Previously we started with undef and did a final merge with the passthru at the end.
