[dev.typeparams] cmd/compile: inlining tweaks for toolstash
This CL makes to minor changes motivated by making it easier to make
large-scale changes to the inliner while satisfying toolstash -cmp:
1. When creating inlining variables, make sure to preserve the
AutoTemp flag. This is necessary so that temporary variables
introduced by rewriting f(g()) calls during typecheck stay autotemp
after inlining and are (correctly) omitted from DWARF debugging
information.
2. When sorting variables for stack frame layout, use a stable
sort. This ensures that layout is insensitive to whether deadcode
elimination happens before or after inlining.
