Vector frontend - part 2

[lekcyjna123]

Here is a second part of vector frontend implementation where I take all modules implemented in #417 and connect them into one block similar to Scheduler. Data are now correctly delivered from integer scheduler to vector reservation station. Next step will be to prepare backend to which these instructions will be put and next executed.

Added:

• VectorAllocRename
• VectorFrontend
• VectorMemoryVVRSSpliter
• VectorTranslators (main block and EEW, LMUL, RP3, IMM)
• VVRS
• Scoreboard
• Register
• RegisterPipe
• ShiftRegister
• PriorityUniqnessChecker

Rework of vector configuration:

• Added VectorUnitConfiguration class
• added VectorParameters as field in GenParams

Miscellany:

• MethodBrancherIn (syntax sugar for calling methods under different branches of m.If)
• NotMethod (to workaround problems with single_caller and SimpleTestCircuit)
• MethodMock class (wrapper over TestbenchIO(Adapter())
