*	[AVR] Expand 8/16-bit multiplication to libcalls on MCUs that don't have ↵	Dylan McKay	2019-01-18	1	-0/+28
	hardware MUL This change modifies the LLVM ISel lowering settings so that 8-bit/16-bit multiplication is expanded to calls into the compiler runtime library if the MCU being targeted does not support multiplication in hardware. Before this, MUL instructions would be generated on CPUs like the ATtiny85, triggering a CPU reset due to an illegal instruction at runtime. First raised in https://github.com/avr-rust/rust/issues/124. llvm-svn: 351523
