[PATCH] [lsan] [mips] adding support of lsan for mips/mipsel arch

[Kumar Sukhani]

Thanks for your comments. I will try to update the patch for MIPS64. 
Few people are also working on 32-bit MSAN and 32-bit TSAN for MIPS.
can anyone please comment on them, as we don't see i386 implementation of those sanitizers also.
