RISC-V: Make xtheadcondmov-indirect tests robust against instruction reordering

Fixes: c1bc7513b1d7 ("RISC-V: const: hide mvconst splitter from IRA")

A recent change broke the xtheadcondmov-indirect tests, because the order of
emitted instructions changed. Since the test is too strict when testing for
a fixed instruction order, let's change the tests to simply count instruction,
like it is done for similar tests.
