[x86] avoid infinite loop from SoftenFloatOperand (PR34866)

Legalization of fp128 assumes things that we should have asserts for,
so that's another potential improvement.

[AVR] Implement LPMWRdZ pseudo-instruction's expansion.

FIXME: implementation is mostly copy-pasted from LDWRdPtr, so we should
refactor a bit and unify the two

[AVR] Insert JMP for long branches

Previously, on long branches (relative jumps of >4 kB), an assertion
failure was hit, as AVRInstrInfo::insertIndirectBranch was not
implemented. Despite its name, it is called by the branch relaxator
for *all* unconditional jumps.

[AVR] Fix displacement overflow for LDDW/STDW

In some cases, the code generator attempts to generate instructions such as:

lddw r24, Y+63

which expands to:

ldd r24, Y+63
ldd r25, Y+64 # Oops! This is actually ld r25, Y in the binary

This commit limits the first offset to 62, and thus the second to 63.
It also updates some asserts in AVRExpandPseudoInsts.cpp, including for
INW and OUTW, which appear to be unused.

[TTI] Fix getGEPCost() for geps with a single operand.

Previously this would sporadically crash as TargetType
was never initialized. We special-case the single-operand
case returning earlier and trying to mimic the behaviour of
isLegalAddressingMode as closely as possible.
