Than McIntosh 9372166faa cmd/compile: fix DWARF type symbol buglet ... The code that generates the list of DWARF variables for a function (params and autos) will emit a "no-location" entry in the DWARF for a user var that appears in the original pre-optimization version of the function but is no longer around when optimization is complete. The intent is that if a GDB user types "print foo" (where foo has been optimized out), the response will be "<optimized out>" as opposed to "there is no such variable 'foo'). This change fixes said code to include vars on the autom list for the function, to insure that the type symbol for the variable makes it to the linker. Fixes #22941.
