[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!

[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
