[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!

COFF: include archive name in LTO object name Summary: In the ELF linker, we create the buffer identifier for bitcode files by appending the object name to the archive name. This change makes the COFF linker do the same. Without the change, ThinLTO builds can fail with an error message about multiple ThinLTO modules per object file, caused by object files contained in different archives having the same name.

[COFF] don't mark lazy symbols as used in regular objects Summary: r338767 updated the COFF and wasm linker SymbolTable code to be strutured more like the ELF linker's. That inadvertedly changed the behavior of the COFF linker so that lazy symbols would be marked as used in regular objects. This change adds an overload of the insert() function, similar to the ELF linker, which does not perform that marking.

[LLD][COFF] use offset in archive to disambiguate archive members Summary: Archives can contain multiple members with the same name. This would cause ThinLTO links to fail ("Expected at most one ThinLTO module per bitcode file"). This change implements the same strategy we use in the ELF linker: make the offset in the archive part of the module name so that names are unique.
