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).
