r600g: Workaround for a harware bug with nested loops on Cayman
There is a hardware bug on Cayman where a BREAK/CONTINUE followed by
LOOP_STARTxxx for nested loops may put the branch stack into a state
such that ALU_PUSH_BEFORE doesn't work as expected. Workaround this
by replacing the ALU_PUSH_BEFORE with a PUSH + ALU
Fixes piglit tests EXT_transform_feedback/order*
v2: Use existing loop count and improve comment
v3: [Vadim Girlin] Set jump address for PUSH instructions
NOTE: This is a candidate for the 9.1 branch
