[PATCH] D53323: [PowerPC][NFC] Fix bugs in r+r to r+i conversion

[Qing Shan Zhang via Phabricator via llvm-commits]

The patch will disable some valid transformation post RA(i.e. LXSDX --> LXSD if the def reg is valid for D-form). We can continue to check the dst Reg to see if it is valid, instead of disabling it completely.
