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

[Kostya Serebryany]

msan and especially tsan are very hard on 32-bit.
Please do not even attempt 32-bit MIPS tsan/msan before making them work on
64-bit MIPS (should be easy)
*and* on 32-bit x86 (hard, complex, low value/priority, the resulting tool
will be very restricted).

asan on 32-bit MIPS is a different story -- it should be easy.
