[testsuite] Add effective target large_initializer
When compiling builtin-object-size-21.c for nvptx, cc1 times out while
emitting the initializer for global variable xm3_3.
With x86_64, we are able to emit the initializer with a few lines of
assembly:
...
xm3_3:
.byte 0
.zero 9223372036854775803
.byte 1
.byte 2
.byte 3
...
but with nvptx, we don't have some something similar available, and thus
generate:
...
.visible .global .align 1 .u32 xm3_3[2305843009213693952] =
{ 0, 0, 0, ...
...
Introduce an effective target large_initializer, returning false for nvptx,
and require it for test-cases with large initializers.
Tested on nvptx with make check-gcc.
