[PATCH] D138157: Make -fsanitize=scudo use scudo_standalone. Delete check-scudo.

[Mitch Phillips via Phabricator via cfe-commits]

hctim updated this revision to Diff 479693.
hctim added a comment.

Lots of places in scudo_standalone depend on GWP-ASan, and it seems far more reasonable to make COMPILER_RT_HAS_GWP_ASAN mean "is GWP-ASan actually going to be built", rather than checking three variables in all the places.

Give the same treatment to COMPILER_RT_HAS_SCUDO_STANDALONE.

This should fix the reviewer problems that were identified:

1. scudo_standalone's cmake rules don't get generated when COMPILER_RT_BUILD_SANITIZERS=Off or COMPILER_RT_SANITIZERS_TO_BUILD does not contain scudo_standalone.
2. check-scudo_standalone's cmake rules don't get generated when COMPILER_RT_INCLUDE_TESTS=Off.
