[llvm] [TableGen] Split large printInstruction() for NVPTX to avoid compiler limits (PR #218530)

[Kazu Hirata via llvm-commits]

LGTM with a couple of inline comments on hoisting `llvm::erase_if`.

Also, please update the last paragraph of the PR/commit description:

    The mechanism triggers for any target with overflow instructions, so it is not NVPTX-specific

to reflect the opt-in `UseFunctionPointerTable` flag in `Target.td`.
