Max Moroz 330496c3fc [libFuzzer] Disable experimental clang coverage support by default. 
Summary:
It can be enabled via "-use_clang_coverage=1" flag. Reason for disabling:
libFuzzer resets Clang Counters and makes it impossible to generate coverage
report for a regular fuzz target (i.e. not standalone build).

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.
