[LLD] Mark a number of x86 only tests to require x86 Noticed while testing for an out of tree target. There are probably more tests that should be so marked. I'm not sure who owns these tests so I've added a few names I recognise from the recent history. With advice from probinson, ruiu, rafael and dramatically improved by davidb. Thank you all!

[lld][COFF][ELF][WebAssembly] Replace --[no-]threads /threads[:no] with --threads={1,2,...} /threads:{1,2,...} --no-threads is a name copied from gold. gold has --no-thread, --thread-count and several other --thread-count-*. There are needs to customize the number of threads (running several lld processes concurrently or customizing the number of LTO threads). Having a single --threads=N is a straightforward replacement of gold's --no-threads + --thread-count. --no-threads is used rarely. So just delete --no-threads instead of keeping it for compatibility for a while. If --threads= is specified (ELF,wasm; COFF /threads: is similar), --thinlto-jobs= defaults to --threads=, otherwise all available hardware threads are used. There is currently no way to override a --threads={1,2,...}. It is still a debate whether we should use --threads=all. Reviewed By: rnk, aganea Differential Revision: https://reviews.llvm.org/D76885

[ThinLTO] Allow usage of all hardware threads in the system Before this patch, it wasn't possible to extend the ThinLTO threads to all SMT/CMT threads in the system. Only one thread per core was allowed, instructed by usage of llvm::heavyweight_hardware_concurrency() in the ThinLTO code. Any number passed to the LLD flag /opt:lldltojobs=..., or any other ThinLTO-specific flag, was previously interpreted in the context of llvm::heavyweight_hardware_concurrency(), which means SMT disabled. One can now say in LLD: /opt:lldltojobs=0 -- Use one std::thread / hardware core in the system (no SMT). Default value if flag not specified. /opt:lldltojobs=N -- Limit usage to N threads, regardless of usage of heavyweight_hardware_concurrency(). /opt:lldltojobs=all -- Use all hardware threads in the system. Equivalent to /opt:lldltojobs=$(nproc) on Linux and /opt:lldltojobs=%NUMBER_OF_PROCESSORS% on Windows. When an affinity mask is set for the process, threads will be created only for the cores selected by the mask. When N > number-of-hardware-threads-in-the-system, the threads in the thread pool will be dispatched equally on all CPU sockets (tested only on Windows). When N <= number-of-hardware-threads-on-a-CPU-socket, the threads will remain on the CPU socket where the process started (only on Windows). Differential Revision: https://reviews.llvm.org/D75153

[lld] Avoid creating files outside of work directory. Summary: A test is passing `-o -` to lld in the hope of writing the output to standard out but that is not the case. Instead it creates a file named `-.lto.o`. This fixes it by creating a temporary file in the work directory. Differential Revision: https://reviews.llvm.org/D75605

[LLD][ELF] Use offset in thin archives to disambiguate thinLTO members This is fixing a thinLTO module collision issue for thin archives. The problem is that we always use a zero offset to name members in a thin archive and that causes the following build error: ld.lld: error: Expected at most one ThinLTO module per bitcode file which happens to a thin archive that has two members with the same object file name (whose paths will be ignored by thinLTO driver) The fix here is to use real member offset instead as is done for non-thin archives.
