Toolchain+Ports: Update LLVM to 14.0.1
Besides a version bump, the following changes have been made to our toolchain infrastructure: - LLVM/Clang is now built with -march=native if the host compiler supports it. An exception to this is CI, as the toolchain cache is shared among many different machines there. - The LLVM tarball is not re-extracted if the hash of the applied patches doesn't differ. - The patches have been split up into atomic chunks. - Port-specific patches have been integrated into the main patches, which will aid in the work towards self-hosting. - <sysroot>/usr/local/lib is now appended to the linker's search path by default. - --pack-dyn-relocs=relr is appended to the linker command line by default, meaning ports take advantage of RELR relocations without any patches or additional compiler flags. The formatting of LLVM port's package.sh has been bothering me, so I also indented the arguments to the CMake invocation.

Subject: [PATCH 5/8] [libc++] Add support for SerenityOS
|
||||
|
||||
This commit teaches libc++ about what features are available in our
|
||||
LibC, namely:
|
||||
* We do not have locale support, so no-op shims should be used in place
|
||||
of the C locale API.
|
||||
* The number of errno constants defined by us is given by the value of
|
||||
the `ELAST` macro.
|
||||
* Multithreading is implemented though the pthread library.
|
||||
* Aligned memory allocation is provided by the MSVCRT-like
|
||||
`_aligned_{malloc,free}` functions.
|
||||
|
||||
Adds a hack for a header not found error when including
|
||||
`<initializer_list>` inside the SerenityOS kernel.
|
||||
|
||||
Makes libc++ use its builtin character type table instead of the one
|
||||
provided by LibC as it is incomplete.
