Subject: [PATCH] [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.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [Driver] Add support for SerenityOS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds support for the `$arch-pc-serenity` target to the Clang front end.
This makes the compiler look for libraries and headers in the right
places, and enables some security mitigations like stack-smashing
protection and position-independent code by default.

Subject: [PATCH] [Driver] Default to -ftls-model=initial-exec on SerenityOS
This is a hack to make Clang use the initial-exec TLS model instead of
the default local-exec when building code for Serenity.
This patch should be removed when we implement proper TLS support.

Subject: [PATCH] [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.
