SLSR: Use UnknownAddressSpace instead of default

Authored by arsenm on Apr 25 2016, 8:51 PM.



In the case where isLegalAddressingMode is used for cases
not related to addressing modes, such as pure adds and muls,
it should not be using address space 0. LSR already passes -1
as the address space in these cases.

Maybe change the title to be "... instead of default for pure arithmetic instructions". Otherwise, LGTM!
