[nvptx] Add march alias for misa
The target option misa has the following description:
...
$ gcc --target-help 2>&1 | grep misa
-misa= Specify the PTX ISA target architecture to use.
...
The name misa is somewhat poorly chosen. It suggests that for a use
-misa=sm_30, sm_30 is the name of a specific Instruction Set Architecture.
Instead, sm_30 is the name of a specific target architecture in the generic
PTX Instruction Set Architecture.
Futhermore, there's mptx, which also has ISA in the description:
...
-mptx= Specify the PTX ISA version to use.
...
Add the more intuitive alias march for misa:
...
$ gcc --target-help 2>&1 | grep march
-march= Alias: Same as -misa=.
...
Tested on nvptx.
