Bjorn Pettersson
0676acb6fd [test] Switch to use -passes syntax in a bunch of test cases 
Should cover most of the tests for GVN, GVNHoist, GVNSink, GlobalOpt,
GlobalSplit, InstCombine, Reassociate, SROA and TailCallElim that
had not been updated earlier.

f3a928e233 [opt] Don't translate legacy -analysis flag to require<analysis> 
Tests relying on this should explicitly use -passes='require<analysis>,foo'.

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

Will be re-reverting again.

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.

3459d6ead5 Update BasicAliasAnalysis to understand that nothing aliases with undef values. 
It got this in some cases (if one of them was an identified object), but not in all cases.

This caused stores to undef to block load-forwarding in some cases, etc.

Added test to Transforms/GVN to verify optimization occurs as expected.
