[PATCH] c++: Fix g++.dg/ext/attr-section2.C etc. with Solaris/SPARC as

[Rainer Orth]

The new g++.dg/ext/attr-section2*.C tests FAIL on Solaris/SPARC with the
native assembler:

+FAIL: g++.dg/ext/attr-section2.C  -std=c++14  scan-assembler .(section|csect)[ 
\\\\t]+.foo
+FAIL: g++.dg/ext/attr-section2.C  -std=c++17  scan-assembler .(section|csect)[ 
\\\\t]+.foo
+FAIL: g++.dg/ext/attr-section2.C  -std=c++20  scan-assembler .(section|csect)[ 
\\\\t]+.foo

The problem is that the SPARC assembler requires the section name to be
double-quoted, like

        .section        ".foo%_Z3varIiE",#alloc,#write,#progbits

This patch allows for that.  At the same time, it quotes literal dots in
the REs.

Tested on sparc-sun-solaris2.11 (as and gas) and i386-pc-solaris2.11 (as
and gas).

Ok for trunk?

        gcc/testsuite:
        * g++.dg/ext/attr-section2.C (scan-assembler): Quote dots.  Allow
        for double-quoted section name.
        * g++.dg/ext/attr-section2a.C: Likewise.
        * g++.dg/ext/attr-section2b.C: Likewise.
