Than McIntosh 79e03a9281 cmd/compile: include register-resident output params in DWARF-gen
During the register ABI work, a change was made in CL 302071 to
"stackframe" to treat register-resident output parameter (PARAMOUT)
variables that same as locals, which meant that if they were unused,
we'd delete them from the "Dcl" slice. This has the effect of making
them invisible to DWARF generation later on in the pipeline, meaning
that we don't get DIEs for them in the debug info. This patch fixes
the problem by capturing these params prior to optimization and then
adding them back in for consideration when we're processing the
params/locals of a function during DWARF generation.

Fixes #48573.
