[AVR] [MSP430] Code gen improvements for 8 bit and 16 bit targets
Hi All,
While implementing a custom 16 bit target for academical and demonstration purposes, I unexpectedly found that LLVM was not really ready for 8 bit and 16 bit targets. Let me expose why.
Target backends can be divided into two major categories, with essentially nothing in between:
Type 1: The big 32 or 64 bit targets. Heavily pipelined with expensive branches, running at clock
