gcc: drop placement new workaround for old bootstrap compilers

Browse Source 
Since r15-4719-ga9ec1bc06bd3cc, we require GCC 5.4, so a workaround for
< GCC 4.3 is long-obsolete. Before that, we required GCC 4.8.3 too.

i.e. it shouldn't be possible to build GCC with such a compiler for
quite some time.

gcc/ChangeLog:
	PR libstdc++/29286
	* Makefile.in (ALIASING_FLAGS): Drop.
	* configure: Regenerate.
	* configure.ac: Drop -fno-strict-aliasing workaround for < GCC 4.3.

gcc/d/ChangeLog:

	* Make-lang.in (ALL_DFLAGS): Don't use ALIASING_FLAGS.
