This speeds up RegAllocBasic by 20%, not counting releaseMemory which becomes
way faster.

vpush instructions to save / restore VFP / NEON registers like this:
vpush {d8,d10,d11}
vpop {d8,d10,d11}

vpush and vpop do not allow gaps in the register list.

uses of the function's blocks with undef. This code isn't needed,
because BasicBlock's destructor handles such uses. Also, undef isn't
correct, since blockaddresses may still be used for comparisons
with null.

Remove target specific node MipsISD::CMov, which is not used because all conditional moves are directly matched using tablegen patterns. If there's a need in the future, we can introduce it again

The last uses of these functions were removed in r113852 when LazyValueInfo was permanently enabled and removed the need for them.
