New Revision: 61831

URL: http://llvm.org/viewvc/llvm-project?rev=61831&view=rev
Log:
Now that fold-pcmpeqd-0.ll is effectively testing that scheduling helps
avoid the need for spilling, add a new testcase that tests that the
pcmpeqd used for V_SETALLONES is changed to a constant-pool load as
needed.
