[LLDB][MIPS] Add mips cores in cores_match () in ArchSpec.

[slthakur]

Summary

This patch:

• Allows mips32 cores to match with any mips32/mips64 cores.
• Allows mips32r2 cores to match with core only up-to mips32r2/mips64r2.
• Allows mips32r3 cores to match with core only up-to mips32r3/mips64r3.
• Allows mips32r5 cores to match with core only up-to mips32r3/mips64r5.
• Allows mips32r6 core to match with only mips32r6/mips64r6 or mips32/mips64.

Looks good.
