[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.

[llvm][NVPTX] Strip unneeded '+0' in PTX load/store (#113017)
Remove the extraneous '+0' immediate offset part in PTX load/stores, to
improve readability of output PTX code.

NVPTX: fix test failures under ptxas-12.0.
(Because ptxas-12 no longer supports 32-bit.)
Fixes c5b11a710e01304908e3f320e40bc9da9f6a8de4 and 8da3a8f550d0b266411b2dc177dff8591ee86cb2.

[NVPTX] fixup support for over-aligned parameters (#92457)
This extends the NVPTX support for over-aligned parameters and return
values in a few related ways:
- Support for `alignstack` attribute, as an alternative to legacy nvvm
`!"align"` metadata entries. While we still maintain the legacy support,
long term it might be nice to auto-upgrade to `alignstack`.
- Check the alignment info when emitting the parameter list to prevent a
mismatch between alignment of caller and callee, which would previously
cause a fatal error for `ptxas`.
- Check the alignment info when emitting loads for parameters,
potentially enabling better vectorization.
