[llvm-dev] Supporting external MCContext in MMI

[Hendrik Greving via llvm-dev]

Hi we have something like an external driver that likes to own MCInst data
externally, i.e. outside from LLVM. By default, the
MachineModuleInfo/WrapperPass creates its own context in the constructor
of MachineModuleInfo. MMI's context is used throughout codegen. When using
a MCStreamer with an external context one can achieve almost what we want,
because the streamer's context is used to create MCInst, but not all data
will be owned by the streamer's context. For example symbols are still
owned by MMI's context.

I'm suggesting to do something like https://reviews.llvm.org/D91313
providing the ability to make MMI use an external context. Would this be
something that somebody would review and ok?

Thanks in advance, Hendrik.
