[gdb/testsuite] Fix local-static.exp with g++-4.8

With g++-4.8, I see:
...
(gdb) PASS: gdb.cp/local-static.exp: c++: print free_inline_func(void)
print 'S::method()'::S_M_s_var_int^M
No symbol "S_M_s_var_int" in specified context.^M
(gdb) FAIL: gdb.cp/local-static.exp: c++: print 'S::method()'::S_M_s_var_int
...

The variable is declared like this (showing pruned .ii):
...
void S::method ()
{
  static int S_M_s_var_int = 4;
}
...

But the DWARF generated for the variable is encapsulated in an unnamed lexical
block:
...
 <1><121>: Abbrev Number: 5 (DW_TAG_structure_type)
    <122>   DW_AT_name        : S
    ...
 <2><14f>: Abbrev Number: 6 (DW_TAG_subprogram)
    ...
    <150>   DW_AT_name        : (indirect string, offset: 0x599): method
    <156>   DW_AT_linkage_name: (indirect string, offset: 0x517): \
                                _ZN1S6methodEv /* demangled: dS::method() */
    ...
 <1><3f8>: Abbrev Number: 21 (DW_TAG_subprogram)
    <3f9>   DW_AT_specification: <0x14f>
    ...
    <3fe>   DW_AT_low_pc      : 0x4004fc
    <406>   DW_AT_high_pc     : 0x2c /* 0x400528 */
    ...
 <2><418>: Abbrev Number: 17 (DW_TAG_formal_parameter)
    <419>   DW_AT_name        : (indirect string, offset: 0x68a): this
    ...
 <2><424>: Abbrev Number: 18 (DW_TAG_lexical_block)
    <425>   DW_AT_low_pc      : 0x400508
    <42d>   DW_AT_high_pc     : 0x1e /* 0x400526 */
 <3><435>: Abbrev Number: 22 (DW_TAG_variable)
    <436>   DW_AT_name        : (indirect string, offset: 0x29d): S_M_s_var_int
...
which has the effect that the variable is not addressable unless the program
counter is in the range of the lexical block.

This is caused by gcc PR debug/55541, which was fixed in gcc 5.

Mark in total 225 FAILs as XFAIL.

Tested on x86_64-linux.
