+Attached a patch for x86 static case. I ran runtime tests, and my own
+in a large loop and with exceptions. Please let me know if patch is
+acceptable, and if so whether I should merge the two static cases
+(with/without parameters) or leave separate for clarity. Also, I
+wasn't sure how much code space to reserve.

+The microbenchmark goes from about 17 seconds to 11 seconds with the
+patch on my machine.
