Don't treat a partial <def,undef> operand as a read.
Normally, a partial register def is treated as reading the
super-register unless it also defines the full register like this:
%vreg110:sub_32bit<def> = COPY %vreg77:sub_32bit, %vreg110<imp-def>
This patch also uses the <undef> flag on partial defs to recognize
non-reading operands:
%vreg110:sub_32bit<def,undef> = COPY %vreg77:sub_32bit
This fixes a subtle bug in RegisterCoalescer where LIS->shrinkToUses
would treat a coalesced copy as still reading the register, extending
the live range artificially.
My test case only works when I disable DCE so a dead copy is left for
RegisterCoalescer, so I am not including it.

Intelligently split the landing pad block.
We have to be careful when splitting the landing pad block, because the
landingpad instruction is required to remain as the first non-PHI of an invoke's
unwind edge. To retain this, we split the block into two blocks, moving the
predecessors within the loop to one block and the remaining predecessors to the
other. The landingpad instruction is cloned into the new blocks.

Add SplitLandingPadPredecessors().
SplitLandingPadPredecessors is similar to SplitBlockPredecessors in that it
splits the current block and attaches a set of predecessors to the new basic
block. However, it differs from SplitBlockPredecessors in that it's specifically
designed to handle landing pad blocks.
Two new basic blocks are created: one that is has the vector of predecessors as
its predecessors and one that has the remaining predecessors as its
predecessors. Those two new blocks then receive a cloned copy of the landingpad
instruction from the original block. The landingpad instructions are joined in a
PHI, etc. Like SplitBlockPredecessors, it updates the LLVM IR, AliasAnalysis,
DominatorTree, DominanceFrontier, LoopInfo, and LCCSA analyses.

Re-encoded 128-bit AVX versions of SQRT, RSQRT, RCP have 3 operands
instead of 2. They were already defined this way in their regular
version, but not for the intrinsics versions (*_Int), and that would work
for assembly emission but not for object code, since a MachineOperand
would be missing. This commit fix PR10697.
Also removed the {VSQRT,VRSQRT,VRCP}r_Int forms and match the intrinsic
via INSERT_SUBREG+EXTRACT_SUBREG patterns. The same couldn't be done for
memory versions because sse_load_f32/sse_load_f64 operand need special
handling and don't work like regular "addr" operands.

These fixups are handled poorly in general, and should have a single
contiguous range of bits per fixup type, but that's not how they're
