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 8/9] [cmake] Support building shared libLLVM and libClang for
|
|
SerenityOS
|
|
|
|
This patch tells CMake that the --whole-archive linker option should be
|
|
used for specifying the archives whose members will constitute these
|
|
shared libraries.
|
|
|
|
Symbol versioning is disabled, as the SerenityOS loader doesn't support
|
|
it, and the ELF sections that store version data would just waste space.
