[PULL 03/32] target/ppc: Rename variables to avoid local variable shadowing in VUPKPX

[Markus Armbruster]

From: Cédric Le Goater <clg@kaod.org>

and fix such warnings :

  ../target/ppc/int_helper.c: In function ‘helper_vupklpx’:
  ../target/ppc/int_helper.c:2025:21: warning: declaration of ‘r’ shadows a 
parameter [-Wshadow=local]
