[EarlyCSE] Fix crash with expensive checks after D87691
D87691 reordered some checks, which turned out to be unsafe. More
specifically, when examining a store instruction, the check against
getOrCreateResult should be done before attempting to call
isSameMemGeneration. Otherwise a crash in MSSA walker can occur.
This patch restores the order of these calls to what it was originally.
