[PATCH v4 13/15] gdb/testsuite: fix gdb.base/info-types-c++ with clang

[Bruno Larsen <blarsen@redhat.com>]

When g++ compiles nameles structs defined in a typedef, it adds a
DW_AT_linkage_name with the name defined in the typedef.  So when
running gdb.base/info-types-c++.exp by default, we get the following
output

    All defined types:

    File ../../../common/git-repos/binutils-gdb/gdb/testsuite/gdb.base/info-types.c:
    98:     CL;
    42:     anon_struct_t;
    65:     anon_union_t;
    21:     baz_t;
    33:     enum_t;
    56:     union_t;
    52:     typedef enum {...} anon_enum_t;
    45:     typedef anon_struct_t anon_struct_t;
    68:     typedef anon_union_t anon_union_t;

Clang[++] does not add DW_AT_linkage_name, and so it's output looks like
this:

    All defined types:

    File ../../../common/git-repos/binutils-gdb/gdb/testsuite/gdb.base/info-types.c:
    98:     CL;
    21:     baz_t;
    33:     enum_t;
    56:     union_t;
    52:     typedef enum {...} anon_enum_t;
    45:     typedef struct {...} anon_struct_t;
    68:     typedef union {...} anon_union_t;

Which is still correct output for GDB, but shows up as a failure when
running the test. This commit changes the test to allow for this output
when the compiler is clang.
