[PATCH, committed] Fix placement of REG_EQUAL note in pa_emit_move_sequence

[John David Anglin]

The attached change fixes the placement of a REG_EQUAL note when an insert is 
done to load
the most significant bits of a 64-bit constant.

Tested on hppa64-hp-hpux11.11 with no observed regressions.  Committed to 
active branches.
