[PATCH] [sanitizer][MIPS] Implement clone for MIPS

[Sergey Matveev]

Hi, sorry for the delay.

It may be worth adding a note that we don't have proper CFI info here either (same as in x86_64 version). Clang probably supports all the necessary directives now, but it's a lot of code (at least in the mips case) for very marginal benefits, so probably not worth doing.

Note also that the glibc implementation appears to have a few differences between 32 and 64 bit mips, so please double check those to make sure they don't affect us.

Otherwise lgtm.
