(Changing "\[^#/!|@\]*\[#/!|@\]"
     into "\[^#;/!|@\]*\[#;/!|@\]")

The pa/pa.h ASM_COMMENT_START is ";".

This caused a regression for cris-elf which is apparently one of
the few targets to use the *default* value of ";#" for
ASM_COMMENT_START.  A very portable sequence, by the way, too
bad almost all other targets define their own.  FWIW, the port
most of you'd want to look up has "#".

I committed the following, adding a + after the set of matched
comment characters to match any repetition and combination of
them.  The sibling test-case, nested-2.C, had a similar flaw.

	* g++.dg/debug/dwarf2/nested-3.C: Match a sequence
	of asm-comment characters instead of a single one.
	* g++.dg/debug/dwarf2/nested-2.C: Similar.
