Arthur Eubanks cdf50f8461 [NewPM][opt] Run the "default" AA pipeline by default 
We tend to assume that the AA pipeline is by default the default AA
pipeline and it's confusing when it's empty instead.

PR48779

Initially reverted due to BasicAA running analyses in an unspecified
order (multiple function calls as parameters), fixed by fetching
analyses before the call to construct BasicAA.

; NOTE: Assertions have been autogenerated by utils/update_test_checks.py
; To test epilogue-vectorization we need to make sure that the vectorizer actually vectorizes the loop.
; Without a target triple this becomes difficult, unless we force vectorization through user hints.
; Currently user provided vectorization hints prevent epilogue vectorization unless the forced
; VF is the same as the epilogue vectorization VF. To make these tests target independent we'll use a
; trick where both VFs are forced to be the same value. Mismatching VFs are tested in target specific tests.
; RUN: opt -passes='loop-vectorize' -force-vector-width=4 -enable-epilogue-vectorization -epilogue-vectorization-force-VF=4 -S %s | FileCheck %s
; Some simpler cases are found profitable even without triple or user hints.
