Daniel Sanders 4e52366c2a [globalisel][legalizer] G_LOAD/G_STORE NarrowScalar should not emit G_GEP x, 0. ...

Summary:
When legalizing G_LOAD/G_STORE using NarrowScalar, we should avoid emitting
	%0 = G_CONSTANT ty 0
	%1 = G_GEP %x, %0
since it's cheaper to not emit the redundant instructions than it is to fold them
away later.
