[PATCH] D118376: [x86] try harder to scalarize a vector load with extracted integer op uses

[Sanjay Patel via Phabricator via llvm-commits]

spatel updated this revision to Diff 403992.
spatel added a comment.

Patch updated:

1. Fixed formatting (must have an expired flavor of clang-format on my system).
2. Added dedicated/minimal test to show the extra load vs. register transfer trade-off: `@multi_use_load_scalarization`
