[RegAlloc] Relax the split constrain on MBB prolog

[LuoYuanke]

https://reviews.llvm.org/D52052 is to prevent register split on the MBB
which have prolog instructions defining the exec register (or mask register
that activate the threads of a warp in GPU). The constrain seems too
strict, because 1) If the split is allowed, it may fit the free live range
of a physical register, and no spill will happen; 2) The register class of
register that is under splitting may not be the same to the register that
is defined in prolog, so there is no interference with the register being
defined in prolog.
The current code has another small issue. The MBB->getFirstNonDebugInstr()
just skip debug instructions, but SA->getFirstSplitPoint(Number) would skip
label and phi instructions. This cause some MBB with label instruction being
taken as prolog.
This patch is to relax the split constrain on MMB with prolog by checking
if the register defined in prolog has the common register class with the
register being split. It allow the split if the register defined in prolog
is physical register or there is no common register class.

Where does it spill now? I am afraid we would have the same problem original patch was fixing: spilling/realoading with a wrong exec mask.

[LuoYuanke]

It spills at the entry of the function where there is no prolog instructions. The output remains the same after greedy register allocation.
It seems both SplitKit and InlineSpiller respect the prolog when inserting split or spill instructions, so the functionality should be ensured.

[rampitec]

Then where is restore? Add a second run line and generate full checks after greedy maybe?

[arsenm]

This -NOT check is basically worthless and breaks on debug message change. This needs to check something that is emitted

[LuoYuanke]

Revise the test. The spill restore is after the $exec = IMPLICIT_DEF.
