2020-11-27	factorize SEL(x, OP(y,z), y) into OP(SEL(x, z, 0), y)	Luc Van Oostenryck	1	-1/+0
	'Factorize' and expression like: x ? (y \| z) : y; into (x ? z : 0) \| y; and some positional variants as well as replacing '\|' by '+' or '^'. Note: it's not very clear if this is really an improvement but it allows some very nice simplification of 'bits translations'. Note: the same can be done for others operations, for example it can be done for '&' if '0' (the neuter value for '\|', '+' and '^') by '~0' (same with '*' and '1').

2020-11-27	add testscases for 'bits translation' optimization	Luc Van Oostenryck	1	-0/+26
	Add some testcase related to the simplification of expressions like: if (val1 & BIT1) val2 \|= BIT2; into val2 \|= (val1 & BIT1) {SHL/LSR} \|BIT2-BIT1\|; Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
