[NVPTX,test] Change llc -march= to -mtriple=
Similar to 806761a7629df268c8aed49657aeccffa6bca449
-mtriple= specifies the full target triple while -march= merely sets the
architecture part of the default target triple (e.g. Windows, macOS),
leaving a target triple which may not make sense.
Therefore, -march= is error-prone and not recommended for tests without
a target triple. The issue has been benign as we recognize
nvptx{,64}-apple-darwin as ELF instead of rejecting it outrightly.

[NVPTX] use incomplete aggregate initializers (#79062)
The PTX ISA specifies that initializers may be incomplete ([5.4.4.

[NVPTX] use incomplete aggregate initializers (#79062)
The PTX ISA specifies that initializers may be incomplete ([5.4.4.
Initializers](https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#initializers))
> As in C, array initializers may be incomplete, i.e., the number of
initializer elements may be less than the extent of the corresponding
array dimension, with remaining array locations initialized to the
default value for the specified array type.
Emitting initializers in this form is preferable because it reduces the
size of the PTX, in some cases significantly, and can improve compile
time of ptxas as a result.
