[nvptx] Use '%' as register prefix
The percentage sign as first character of a ptx identifier can be used to
avoid name conflicts, e.g., between user-defined variable names and
compiler-generated names.
The insn nvptx_uniform_warp_check contains register names without '%' prefix,
which potentially could lead to name conflicts with user-defined variable
names.
Fix this by adding a '%' prefix, more specifically a '%r_' prefix to avoid a
name conflict with ptx special registers.
Tested on x86_64 with nvptx accelerator.
