[PATCH 2/9] nvptx: Re-enable "ptxas times out" test cases

[Thomas Schwinge <thomas@codesourcery.com>]

These are all quick to compile and generally PASS with:

    $ ptxas --version
    ptxas: NVIDIA (R) Ptx optimizing assembler
    Copyright (c) 2005-2018 NVIDIA Corporation
    Built on Sun_Sep__9_21:06:46_CDT_2018
    Cuda compilation tools, release 10.0, V10.0.145

(Tested 'gcc.c-torture/compile/920501-4.c' with 'dg-require-stack-size' defused
as per "nvptx: stack size limits are relevant for execution only".)

Only 'gcc.c-torture/compile/limits-fndefn.c' now generally FAILs (but not due
to "ptxas times out"), with:

    ptxas limits-fndefn.o, line 8; fatal   : Parsing error near '.visible': syntax error
    ptxas fatal   : Ptx assembly aborted due to errors
    nvptx-as: ptxas returned 255 exit status

Work around that by '-Wa,--no-verify'; to be analyzed further, later on.

        gcc/testsuite/
        * gcc.c-torture/compile/920501-4.c: Re-enable nvptx
        "ptxas times out" variants.
        * gcc.c-torture/compile/921011-1.c: Likewise.
