#     powerpc: Fix update form addressing in inline assembly
#     
#     In several places, inline assembly uses the "%Un" modifier
#     to enable the use of instruction with update form addressing,
#     but the associated "<>" constraint is missing.
#     
#     As mentioned in previous patch, this fails with gcc 4.9, so
#     "<>" can't be used directly.
#     
#     Use UPD_CONSTR macro everywhere %Un modifier is used.
