Pretty mechanical change here. Just replacing all the std::error_code() with
llvm::Error() and make_dynamic_error_code with make_error<GenericError>

In trying to fix the leaks in the MachO lld codebase, we need to have
a better model for file and atom ownership. Having the context own
everything seems like the simplest model, so change all the passes to
allocate File's on the context instead of owning files as a member.

When we do debug printing of atoms, they expect their parent file
to have an ordinal. Right now we trigger a bunch of asserts.
This doesn't actually manifest in differences in any real tests, but
even if the only thing it does is improve debuggability then its still
useful.

None of the implementations replace the SimpleFile with some other file,
they just modify the SimpleFile in-place, so a direct reference to the
file is sufficient.

I believe this patch eliminates all remaining uses of _context
or _linkingContext variable names. Consistent naming improves
readability.

Arm code has two instruction encodings "thumb" and "arm". When branching from
one code encoding to another, you need to use an instruction that switches
the instruction mode. Usually the transition only happens at call sites, and
the linker can transform a BL instruction in BLX (or vice versa). But if the
compiler did a tail call optimization and a function ends with a branch (not
branch and link), there is no pc-rel BX instruction.
The ShimPass looks for pc-rel B instructions that will need to switch mode.
For those cases it synthesizes a shim which does the transition, then modifies
the original atom with the B instruction to target to the shim atom.
