[Patch][testsuite] Fix a few test cases

Hi,
Here are a few test tweaks. In 921202-1.c, if STACK_SIZE is used then
VLEN will blow the stack with 64bit longs. e.g. if STACK_SIZE == 512K
then 3 arrays of 32767 longs means at a minimum 767K of stack will be
used at -O0. In pr51447.c, the rbx global register is clobbering the rbx
of main's caller, which can cause test case crashes on return.
2014-12-12 Ryan Mansfield <rmansfield@qnx.com>
* gcc.c-torture/execute/921202-1.c: Adjust VLEN.
* gcc.c-torture/execute/pr51447.c: Restore rbx for x86-64.
* gcc.dg/cpp/trad/include.c: Exclude QNX targets.
OK?
Regards,
Ryan Mansfield
