MIPS[64]: Skip regress/regress-165637 in debug.

The timeout in the test is close to execution time in debug mode so it
fails occasionally. The test is measuring array slice algorithm
performance but changes unrelated to it affect the test result in debug
mode, therefore it should be skipped.

BUG=v8:7726
TEST=regress/regress-165637
