Add a patch to let llvm's InstrProfiling modules know serenity supports all the Unix-y features required to make -fprofile-instr-generate and -fcoverage-mapping work properly on target.

Subject: [PATCH 1/9] [Support] Add support for building LLVM on SerenityOS
|
|
|
|
Adds SerenityOS `#ifdef`s for platform-specific code.
|
|
|
|
We stub out wait4, as SerenityOS doesn't support querying a child
|
|
process's resource usage information.
