To provide mapping between standard and microMIPS R6 variants of the
`sw` command we have to rename SWSP_xxx commands from "sw" to "swsp".
Otherwise `tablegen` starts to show the error `Multiple matches found
for `SW'`. After that to restore printing SWSP command as `sw`, I add
an appropriate `MipsInstAlias` instance.
We also need to implement "size reduction" for microMIPS R6. But this
task is for separate patch. After that the `micromips-lwsp-swsp.ll` test
case will be extended.

ld and sd when assembled for the O32 ABI expand to a pair of 32 bit word loads
or stores using the specified source or destination register and the next
register.
This patch does not add support for the cases where the offset is greater than
a 16 bit signed immediate as that would lead to a wrong/misleading error
message as the assembler would report "instruction requires a CPU feature
not currently enabled" for ld & sd for MIPS64 when their offset is not a signed
16 bit number.
This fixes PR/29159.
Thanks to Sean Bruno for reporting this issue!
