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

            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.
