Florian Hahn	e248d69036	Recommit "[LAA] Support pointer phis in loop by analyzing each incoming pointer." SCEV does not look through non-header PHIs inside the loop. Such phis can be analyzed by adding separate accesses for each incoming pointer value. This results in 2 more loops vectorized in SPEC2000/186.crafty and avoids regressions when sinking instructions before vectorizing. Fixes PR50296, PR50288.

Recommit "[LAA] Support pointer phis in loop by analyzing each incoming pointer."

SCEV does not look through non-header PHIs inside the loop. Such phis
can be analyzed by adding separate accesses for each incoming pointer
value.

This results in 2 more loops vectorized in SPEC2000/186.crafty and
avoids regressions when sinking instructions before vectorizing.

Fixes PR50296, PR50288.
