This enables the LLD_IN_TEST=2 testing mode for ``` path/to/llvm-lit -sv --param RUN_LLD_MAIN_TWICE=1 lld/test/ELF ``` When `Fatal` is called, `RunSafely` will return false. For the first invocation in LLD_IN_TEST=2 mode, `inTestOutputDisabled` is true and lld will not write to stdout/stderr, making many tests fail. (This essentially discourages `Fatal` calls in the source code.) Add XFAIL: main-run-twice to these tests similar to https://reviews.llvm.org/D112898 for Mach-O ``` comment="This test intentionally checks for fatal errors, and fatal errors aren't supported for testing when main is run twice." xargs </tmp/0 sed -Ei "1s/(;|#|\/\/) REQUIRES: .*/\0\n\1 "$comment"\n\1 XFAIL: main-run-twice/;t;1s/^/# "$comment"\n# XFAIL: main-run-twice\n/" ```
