[patch/rfc] Always define PC_IN_CALL_DUMMY et.al.

I've checked this in.  Also tested on a Solaris 2.7 machine. 
Before/after test results were pretty bad:

                 === gdb Summary ===

# of expected passes            7803
# of unexpected failures        250
# of unexpected successes       2
# of expected failures          65
# of unresolved testcases       18
# of untested testcases         3
# of unsupported tests          2

but identical.
