New test filters

[DurieuxPol]

Added 2 new test filters:

• MTBlockTestFilter which selects tests based on the given block
• MTPragmaRejectionTestFilter which rejects tests that contain a given pragma
• MTPragmaSelectionTestFilter which selects tests that contain a given pragma

Merci @DurieuxPol !

Why one of the filters rejects while the other filter selects?
That will confuse people (starting by myself :D)

[DurieuxPol]

Because to me, you want to use pragma in tests as flags that specify which tests you don't want to run.
It seems easier than adding a pragma to all the tests you wanna run when you only want to ignore 2 or 3.
But I can change the pragma filter, or even add one that selects pragma instead.

I understand, maybe the name should be more explicit... But to me either the filters do filter out (reject) or select.
In this sense "PragmaTestFilter" could be "AvoidPragmaTestFilter".

[DurieuxPol]

I agree, I should rename it.
Maybe I can do 2 pragma filters, one that rejects pragma, and one that selects ? So that both use cases are considered ?

[guillep]

Oh yes this seems nicer!

Good! Thanks @DurieuxPol !
