Ilya Leoshkevich f5a252ed68 [SanitizerCoverage] Use zeroext for cmp parameters on all targets
Commit 9385aaa848 ("[sancov] Fix PR33732") added zeroext to
__sanitizer_cov_trace(_const)?_cmp[1248] parameters for x86_64 only,
however, it is useful on other targets, in particular, on SystemZ: it
fixes swap-cmp.test.

Therefore, use it on all targets. This is safe: if target ABI does not
require zero extension for a particular parameter, zeroext is simply
ignored. A similar change has been implemeted as part of commit
3bc439bdff ("[MSan] Add instrumentation for SystemZ"), and there were
no problems with it.

Ilya Leoshkevich ea9b82da41 [libFuzzer] Enable for SystemZ
* Add SystemZ to the list of supported architectures.

* XFAIL a few tests.

Coverage reporting is broken, and is not easy to fix (see comment in
coverage.test). Interaction with sanitizers needs to be investigated
more thoroughly, since they appear to reduce coverage in certain cases.

George Karpenkov fa57519e31 [libFuzzer] [NFC] Prefix all run lines with %run
This patch does not do anything, but paves the way for future changes,
where %run command will be expanded into a script performing the testing
on device.

George Karpenkov 10ab2ace13 Move libFuzzer to compiler_rt.
Resulting library binaries will be named libclang_rt.fuzzer*, and will
be placed in Clang toolchain, allowing redistribution.
