Adding tc19_shadowmem.stderr.exp-mips32 to match different output.

Writing to a double is done via two store-word instructions on MIPS platforms.
Thus, Helgrind will report "Possible data race during write of size 4" twice on
subsequent locations on MIPS instead of a single "Possible data race during
write of size 8". New exp file is added to cover this case.
This fixes helgrind/tests/tc19_shadowmem on MIPS.
