[pushed] c++: vector compound literal [PR105187]

[pushed] c++: vector compound literal [PR105187]

[Jason Merrill]

My cleanup in r12-296 cleared TREE_HAS_CONSTRUCTOR on digested class
initializers, but we leave it set for vectors, since we can't wrap them in
TARGET_EXPR.

Tested x86_64-pc-linux-gnu, applying to trunk.

	PR c++/105187

gcc/cp/ChangeLog:

	* typeck2.cc (store_init_value): Allow TREE_HAS_CONSTRUCTOR for
	vectors.

gcc/testsuite/ChangeLog:

	* gcc.c-torture/compile/20050113-1.c: Moved to...
	* c-c++-common/torture/20050113-1.c: ...here.

The test FAILs on i686-linux if neither MMX isn't enabled, can be also
reproduced with
make check-gcc check-g++ RUNTESTFLAGS='--target_board=unix/-m32/-mno-mmx/-mno-sse dg-torture.exp=20050113-1.c'
on x86_64-linux.  Previously the test was in gcc.c-torture/compile/
where -w is added by default.

Tested on x86_64-linux, committed to trunk as obvious.
