[commit/testsuite/obvious] complex.exp: use test_compiler_info

[Michael Elizabeth Chastain]

Here is my nightly test_compiler_info cleanup patch.

Testing: tested with gcc 2.95.3 and 3.3.2, dwarf-2 and stabs+.

I also checked out the setup_xfail.  It's for real.  gcc 2.95.3
-gdwarf-2 generates bad debug info for a structure like this:

  struct
  {
    char c;
    __complex_ float f;
  };

The structure is 9 bytes long, but the debug info is for a 12-byte
structure, as if there is padding between "char c" and "__complex__
float f".

gcc 3.3.2 -dwarf-2 works fine and it's pointless to file a bug report
against gcc 2.95.3.  I just thought I'd mention this.

I am committing this now as an obvious fix.

	Partial fix for PR testsuite/1456.
	* gdb.base/complex.exp: Replace reference to gcc_compiled with
	call to test_compiler_info.
