[PATCH] fix for breakpoint test

[Michael Snyder]

        * gdb.base/break.exp (bp on small function, optimized file):
        Add a second pass pattern.  The behavior differs here between stabs
        and dwarf for one-line functions.  Stabs preserves two line symbols
        (one before the prologue and one after) with the same line number,
        but dwarf regards these as duplicates and discards one of them.
        Therefore the address after the prologue (where the breakpoint is)
        has no exactly matching line symbol, and GDB reports the breakpoint
        as if it were in the middle of a line rather than at the beginning.
