  -----------
  [PowerPC] Do not convert lwz to lwa if the offset is not a multiple of 4

The transform that converts this checks the alignment of the global
object being accessed. However, there was no check for the offset
within the global object which caused the compiler to produce a
DS relocation for an unaligned address.
