[UBSan][MIPS] Adding support of MIPS64 in UBSan testing

[slthakur]

Summary

On mips64 addresses are 40-bit. Where as a 48 bit address is used in TypeCheck/misaligned.cpp.
Using regular expression for that address.

Hm, let's not overcomplicate things and just use

0x{{0+}}123

regexp for address.

LGTM
