[VectorCombine] Fix scalarizeExtExtract for big-endian (#157962)
The scalarizeExtExtract transform assumed little-endian lane ordering,
causing miscompiles on big-endian targets such as AIX/PowerPC under -O3
-flto.
This patch updates the shift calculation to handle endianness correctly
for big-endian targets. No functional change
for little-endian targets.
Fixes #158197.
