[PATCH] D83024: [PGO] Instrument function entry BB by default in IR PGO

[Rong Xu via Phabricator via llvm-commits]

xur updated this revision to Diff 280984.
xur added a comment.

Update the patch after committing the support in a separated patch:
commit 50da55a58534e9207d8d5e31c8b4b5cf0c624175 <https://reviews.llvm.org/rG50da55a58534e9207d8d5e31c8b4b5cf0c624175>

This patch will turn -pgo-instrument-entry to true by default.

Many tests are already submitted with the supporting patch.
This patch will update the rest of tests.

I'm not confident that the test changes are complete as I only tested X86 Linux platforms.
