[Patch] nvptx/nvptx.opt: Update -march-map= for newer sm_{107,110}{,a,f}

[Tobias Burnus]

Nvptx's  -march-map=  maps the specified compute capability sm_...
to -march=... - The idea is that one specifies the actually hardware
and GCC then picks the best supported -march=.

[For every -march=, GCC actually produces different code while JIT is
used to produce the ISA for the hardware to be run.]

This patch honors CUDA 13's renaming of Jetson Thor's compute capability
from 101 to 110. And CUDA 13.4 then added 107 for Rubin GPUs.

OK for mainline?

nvptx/nvptx.opt: Update -march-map= for newer sm_{107,110}{,a,f}
    
Usage of the -march-map=: "Select the closest available '-march=' value
that is not more capable."
    
PTX ISA 9.0 (CUDA 13.0) added SM_110{,a,f} - which is a renamed SM_101
(Jetson Thor).  PTX ISA 9.4 (CUDA 13.4) added SM_107{,a,f} (Rubin).
['a' = ISA for that specific arch only, 'f' stands for the family, only.]
    
Internally, GCC currently generates the same code for >= sm_80 (Ampere);
however, as GCC's -march= also supports sm_89 (Ada), the here added
sm_1xxs will map to sm_89.
    
[Naming note: while ptx code generated for sm_X can also run with sm_Y
if Y > X, code generated for sm_XXXa can (generally) only run on
the specific hardware; and sm_XXXf implies compatibility with only
subsequent targets in the same family.]

gcc/ChangeLog:
    
	* config/nvptx/nvptx.opt (march-map=): Add sm_107{,f,a} and
	sm_110{,f,a}.
