45f860c0dc llvm: backport fixes, fix 32-bit (#5630) 
* --disable-high-entropy-va is not accepted on 32-bit ld, it should be added only on 64-bit.

* New Cygwin linker driver was not passing --large-address-aware on 32-bit

* Microsoft-style calling convention name mangling (such as stdcall Name@N) was disabled on Cygwin, regression from 21.1.  This would have been an issue on x86_64 as well with vectorcall I think

0586ad6beb llvm: update to 21.1.0 
add an msysize patch to deal with the fallout of teaching the Cygwin
driver how to call the linker directly instead of using GCC to do it

670e3bbcfa llvm: install compiler-rt to cygwin rather than msys 
This is in preparation for a future patch that will let Clang call the
linker directly, and it will expect to find compiler-rt in "cygwin".

Also, enable tests.  Disable tests for compiler-rt though, as they cause
build errors due to missing targets for sanitizer tests.

933a7d740b llvm: add README-patches.md to track patches 
Format copied from MINGW-packages/mingw-w64-llvm.  There are getting to
be a bunch of patches, and the effort to upstream them is going well.

808401f0a9 llvm: set LLVM_ENABLE_PIC=OFF in gcc static bootstrap path. 
The LIBCLANG_ENABLE_STATIC_BUILD option is documented as building a static
libclang *in addition to* the shared one.  In order to disable building
the shared library, LLVM_ENABLE_PIC needs to be OFF also.

d4e1e8397f llvm: fix up package depenencies 
This was based off of a clang-built dylib build, so perhaps lld doesn't
need to depend on llvm if it was statically linked, but I think moving
forward we'd be better off with a dylib build once we can do it with the
clang in the repos.

10275b6d72 llvm: don't hack in Cygwin search paths to lld 
This breaks usage of lld for cross compiling, which otherwise actually
works, as opposed to trying to use lld for Cygwin targets at this point.
