[NFC][test] replace empty returns with GTEST_SKIP

[supergrecko]

Summary

Now that gtest has been updated to 1.10 which supports GTEST_SKIP, we can use that over return;

This patch replaces returns with GTEST_SKIP for the todo listings added in https://reviews.llvm.org/rGd122d80b3d1c3ffdfbf6a2168f3d61fa4337facc

LGTM, pending acceptance of https://reviews.llvm.org/D102694.

GTEST_SKIP() may be called in OrcCAPITestBase::SetUp() so that checks can be removed in every separate test.

[NFC][test] replace if clauses in all tests with GTEST_SKIP() in SetUp

That also works, thank you for the suggestion. I've updated the revision accordingly.

[ikudrin]

LGTM, thanks!

I do not have commit access so it'd be great if somebody could land this on my behalf.

Done. Thanks for the patch! :)
