It is possible that the remangled name for an intrinsic already exists with a different (and wrong) prototype within the module.
As the bitcode reader keeps both versions of all remangled intrinsics around for a longer time, this can result in a
crash, as can be seen in https://bugs.llvm.org/show_bug.cgi?id=50923
This patch makes 'remangleIntrinsicFunction' aware of this situation. When it is detected, it moves the version with the wrong prototype to a different name. That version will be removed anyway once the module is completely loaded.
With thanks to @asbirlea for reporting this issue when trying out an lto build with the full restrict patches, and @efriedma for suggesting a sane resolution mechanism.

This patch fixes linker behavior when archive is linked with other inputs
as a library (i.e. when --only-needed option is specified). In this case library
is expected to be normally linked first into a separate module and only after
that linker should import required symbols from the linked library module.

llvm-link should not rely on the '.a' file extension when deciding if input file
should be loaded as archive. Archives may have other extensions (f.e. .lib) or no
extensions at all. This patch changes llvm-link to use llvm::file_magic to check
if input file is an archive.

This patch adds support for archive files as inputs to llvm-link. One
of the use-cases is for OpenMP, where device specific libraries need
to be extracted from libraries containing bundled object files. The
clang-offload-bundler will support extracting these archives, which
will be passed into llvm-link, see https://reviews.llvm.org/D80816.
