nvptx: Re-enable "Stack alignment causes use of alloca" test cases

These generally PASS nowadays, without requiring 'alloca'.

There were two exceptions: 'gcc.dg/torture/stackalign/pr16660-2.c',
'gcc.dg/torture/stackalign/pr16660-3.c', where variants specifying
'-O0' or '-fpic' FAILed with 'ptxas' of, for example, CUDA 10.0 due to:

    nvptx-as: ptxas terminated with signal 11 [Segmentation fault], core dumped

That however is gone with 'ptxas' of, for example, CUDA 11.5 and later.

	gcc/testsuite/
	* gcc.dg/torture/stackalign/global-1.c: Re-enable for nvptx.
	* gcc.dg/torture/stackalign/inline-1.c: Likewise.
	* gcc.dg/torture/stackalign/nested-1.c: Likewise.
	* gcc.dg/torture/stackalign/nested-2.c: Likewise.
	* gcc.dg/torture/stackalign/nested-4.c: Likewise.
	* gcc.dg/torture/stackalign/pr16660-1.c: Likewise.
	* gcc.dg/torture/stackalign/pr16660-2.c: Likewise.
	* gcc.dg/torture/stackalign/pr16660-3.c: Likewise.
	* gcc.dg/torture/stackalign/ret-struct-1.c: Likewise.
	* gcc.dg/torture/stackalign/struct-1.c: Likewise.
