RFR: 8352595: Regression of JDK-8314999 in IR matching [v2]

[Marc Chevalier]

> A lot of tests for the IR framework used `ALLOC` and friends as a check that would run on the Opto assembly by default, but can also run earlier, but that's no longer the case.
> 
> There were two kinds of tests to fix: the ones rather about `ALLOC`, where the used or expected compile phases have to change, and the tests where `ALLOC` were just a check that would run on opto assembly. For this, I tried to keep the spirit of the test using other regexes made for this stage.
