Lei Huang f4ec67822f [PowerPC] Remove the match pattern in the definition of LXSDX/STXSDX 
The match pattern in the definition of LXSDX is xoaddr, so the Pseudo
instruction XFLOADf64 never gets selected. XFLOADf64 expands to LXSDX/LFDX post
RA based on the register pressure. To avoid ambiguity, we need to remove the
select pattern for LXSDX, same as what was done for LXSD. STXSDX also have
the same issue.

Patch by Qing Shan Zhang (steven.zhang).

Nemanja Ivanovic 275853e777 Do not assume that FP vector operands are never legalized by expanding 
This patch ensures that if a floating point vector operand is legalized by
expanding, it is legalized through the stack rather than by calling
DAGTypeLegalizer::IntegerToVector which will cause a failure since the operand
is a non-integer type.

This fixes PR 30715.
