This inserts missing parentheses in the calculation of the comparison
result between two different inferior numbers. The problem was found by
Philipp Rudo.
gdb/ChangeLog:
* thread.c (tp_array_compar): Insert missing parentheses.
gdb/testsuite/ChangeLog:
* gdb.multi/tids.exp: Test "thread apply all".
