Junxian Zhu 24f83ed4e2 cmd/internal/obj/mips: add SEB/SEH instructions
Add support for SEB/SEH instructions, which are introduced in mips32r2.

SEB/SEH can be used to sign-extend byte/halfword in registers directly without passing through memory.

Ref: The MIPS32 Instruction Set, Revision 5.04: https://s3-eu-west-1.amazonaws.com/downloads-mips/documents/MD00086-2B-MIPS32BIS-AFP-05.04.pdf
