RFR: 8350330: C2: PhaseIdealLoop::add_parse_predicate() should mirror GraphKit::add_parse_predicate()

[Roland Westrelin]

`PhaseIdealLoop::add_parse_predicate()` was intented to mirror
`GraphKit::add_parse_predicate()` but it doesn't. That last one checks
`too_many_traps` per bci but the `PhaseIdealLoop` version doesn't. As
demonstrated by the test case, a method can get compiled with a
predicate, take a trap, and get recompiled with the same predicate
many times (up to ~100).
