[PATCH] D145329: AMDGPU: Always split blocks for si_end_cf

[Carl Ritson via Phabricator via llvm-commits]

Sorry for the delay.  I believe D151797 <https://reviews.llvm.org/D151797> should allow this to proceed.

I will also look at adding block splitting to WQM, but I need to take care with this as it can have some unintended effects on reg alloc.
In general we have not had to worry about spilling correctness in graphics for pixel shaders (where WQM occurs) as spilling is generally a no-go for having good performance in graphics.
