softmmu templates: optionally pass CPUState to memory access functions
Optionally, make memory access helpers take a parameter for CPUState instead of relying on global env. On most targets, perform simple moves to reorder registers. On i386, switch from regparm(3) calling convention to standard stack-based version. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
