[PATCH] Remove ignored "xfail" from dg-do compile directives

[Jonathan Wakely]

As documented at https://gcc.gnu.org/onlinedocs/gccint/Directives.html
an "xfail" is ignored for dg-do what unless what==run.

This removes five such ignored uses of xfail in the dg-do directive.
These tests are already expected to XFAIL because of the
dg-excess-errors directives (with optional target selector for the
uclibc ones).

Removing the xfail from the dg-do directive allows { target c++11 }
there instead (if appropriate).

	* testsuite/23_containers/unordered_map/requirements/53339.cc: Remove
	ignored "xfail" from { dg-do compile { xfail selector } } directive.
	* testsuite/23_containers/unordered_multimap/requirements/53339.cc:
	Likewise.
	* testsuite/26_numerics/headers/cmath/
	c99_classification_macros_c++11.cc: Likewise.
	* testsuite/26_numerics/headers/cmath/
	c99_classification_macros_c++98.cc: Likewise.
	* testsuite/26_numerics/headers/cmath/
	c99_classification_macros_c.cc: Likewise.

Tested x86_64-linux, powerpc64-linux, committed to trunk.
