Krzysztof Drewniak 1ce314ce6b [MLIR][GPU][lld] Use LLD bundled in ROCm, removing workaround 
Having clarified that executing the SerializeToHsaco pass can
depend on a ROCm installation, switch from calling lld as a library to
using the copy of lld guaranteed to be included in a ROCm install.

This removes the workaround introduced in D119277

Alexandre Ganea 1e661e583d [MLIR] Temporary workaround for calling the LLD ELF driver as-a-lib 
This fixes the situation described in https://github.com/llvm/llvm-project/issues/53475 with a repro exposed by https://github.com/ROCmSoftwarePlatform/D108850-lld-bug-reproduction

This is purposely just a workaround to unblock users. This could be transplanted to the release/14.x branch if need be. A proper fix will later be provided in https://reviews.llvm.org/D119049.

Alexandre Ganea 83d59e05b2 Re-land [LLD] Remove global state in lldCommon 
Move all variables at file-scope or function-static-scope into a hosting structure (lld::CommonLinkerContext) that lives at lldMain()-scope. Drivers will inherit from this structure and add their own global state, in the same way as for the existing COFFLinkerContext.

See discussion in https://lists.llvm.org/pipermail/llvm-dev/2021-June/151184.html

The previous land f860fe3622 caused issues in https://lab.llvm.org/buildbot/#/builders/123/builds/8383, fixed by 22ee510dac.
