target-ppc: Correct Simple VSR LE Host Inversions
A common pattern in the VSX helper code macros is the use of "x.fld[i]" where
"x" is a VSR and "fld" is an argument to a macro ("f64" or "f32" is passed).
This is not always correct on LE hosts.
This change addresses all instances of this pattern to be "x.fld" where "fld" is:
- "VsrD(0)" for scalar instructions accessing 64-bit numbers
- "VsrD(i)" for vector instructions accessing 64-bit numbers
- "VsrW(i)" for vector instructions accessing 32-bit numbers
Note that there are no instances of this pattern where a scalar instruction
accesses a 32-bit number.
Note also that it would be correct to use "VsrD(i)" for scalar instructions since
the loop index is only ever "0". I have choosen to use "VsrD(0)" instead ... it
seems a little clearer.
