Summary:
Folded mips64-fp-indexed-ls.ll into fp-indexed-ls.ll. To do so, the zext's in
mips64-fp-indexed-ls.ll were changed to implicit sign extensions (performed
by getelementptr). This does not affect the purpose of the test.

Summary:
c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to
dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's
(like the GPR comparisons).
mov[fntz] have been replaced by seleqz and selnez. These instructions
conditionally zero a register based on a bool in a GPR. The results can
then be or'd together to act as a select without, for example, requiring a third
register read port.
mov[fntz].[ds] have been replaced with sel.[ds]
MIPS64r6 currently generates unnecessary sign-extensions for most selects.
This is because the result of a SETCC is currently an i32. Bits 32-63 are
undefined in i32 and the behaviour of seleqz/selnez would otherwise depend
on undefined bits. Later, we will fix this by making the result of SETCC an
i64 on MIPS64 targets.

Summary:
To make this work for both AFGR64 and FGR64 register sets, I've had to make the
instruction definition consistent with the white lie (that it reads the lower
32-bits of the register) when they are generated by expandBuildPairF64().
Corrected the definition of hasMips32r2() and hasMips64r2() to include
MIPS32r6 and MIPS64r6.

When I originally added node RDTSCP_DAG (r207127) I forgot to add
a string name for it in method 'getTargetNodeName'.
No functional change intended.

Summary:
This patch updates both the assembler and the code generator.
MIPS32r6/MIPS64r6 replaces them with maddf.[ds] and msubf.[ds] which are fused
multiply-add/sub operations. We don't emit these yet, this patch only prevents the removed instructions from being emitted.

This patch adds target combine rules to match:
- [AVX] Horizontal add/sub of packed single/double precision floating point
values from 256-bit vectors;
- [AVX2] Horizontal add/sub of packed integer values from 256-bit vectors.

Summary:
The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have
been removed and replaced with GPR-based equivalents. For example:
div $1, $2
mflo $3
is now:
div $3, $1, $2
This patch disables the accumulator-based multiplies and divides for
MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead.
Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the
behaviour of the function.
MipsDelaySlotFiller now invalidates the liveness information when moving
instructions to the delay slot. Without this, divrem.ll will abort since
%GP ends up used before it is defined.

This begins to address cognitive dissonance caused by treating the Note

In general this fixes ambiguity that can arise from using
a different namespace that declares the same symbols as
we do.
One example inside llvm would be:
createIndVarSimplifyPass(..);
Which can be found in:
llvm/Transforms/Scalar.h
and
polly/LinkAllPasses.h

Fixes#19976.
The error log does not contain an error, in case we reject a candidate
without generating a diagnostic message by using invalid<>(...). This is
the case for the top-level region of a function.
The patch comes without a test-case because adding a useful one requires
additional code just for triggering it. Before the patch it would only trigger,
if we try to print the CFG with Scop error annotations.
