Log:
[nvptx] Assert fork has at most one join in nvptx_find_par
With the test-case of PR90009 we run into a SIGSEGV in nvptx_neuter_pars,
because par->join_insn and par->join_block are NULL.
Detect this problem earlier, by adding an assert in nvptx_find_par that
asserts that a fork cannot be paired with more than one join.
Build and tested on x86_64 with nvptx accelerator enabled.
