Chris Tate 21e4c3683f Keep the budget in typed-array length loops that assign their array

A loop to a typed array's length reads the length again on every
iteration, so a body that assigns the array's binding changes the limit
for the next iteration. The strip-mined form took the length once per
block of 64 iterations, and after the body assigned a shorter array it
ran on to the block's end, reading past the new length.

The loop to a typed array's length is now strip-mined only when the
array is a local of the function that the body never assigns
(stableReceiver on the match); others keep the budget and test the
length on every iteration.

New corpus program: native-worker-length-loop-reassign.ts.
