[LLDB][MIPS] Handle false positives for MIPS hardware watchpoints

Description

[LLDB][MIPS] Handle false positives for MIPS hardware watchpoints

SUMMARY:
Last 3bits of the watchpoint address are masked by the kernel. For example, n is 
at 0x120010d00 and m is 0x120010d04. When a watchpoint is set at m, then watch 
exception is generated even when n is read/written. To handle this case, instruction 
at PC is emulated to find the base address of the load/store instruction. This address 
is then appended to the description of the stop-info packet. Client then reads this 
information to check whether the user has set a watchpoint on this address.
