Subject: [MSSA] Remove useless assert. NFC.
X-Git-Tag: llvmorg-4.0.0-rc1~14381
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f23eb70e033e6de28b45c3b2c99e174e940f0b5a;p=platform%2Fupstream%2Fllvm.git

[MSSA] Remove useless assert. NFC.

liveOnEntry is always a MemoryDef; asserting that a MemoryPhi isn't
liveOnEntry, while correct, isn't very helpful. :)
