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

[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.

Recommit "[libFuzzer] Link libFuzzer's own interceptors when other compiler runtimes are not linked." Summary: libFuzzer intercepts certain library functions such as memcmp/strcmp by defining weak hooks. Weak hooks, however, are called only when other runtimes such as ASan is linked. This patch defines libFuzzer's own interceptors, which is linked into the libFuzzer executable when other runtimes are not linked, i.e., when -fsanitize=fuzzer is given, but not others. The patch once landed but was reverted in 8ef9e2bf355d05bc81d8b0fe1e5333eec59a0a91 due to an assertion failure caused by calling an intercepted function, strncmp, while initializing the interceptors in fuzzerInit(). This issue is now fixed by calling libFuzzer's own implementation of library functions (i.e., internal_*) when the fuzzer has not been initialized yet, instead of recursively calling fuzzerInit() again.
