1 registers, 5 instructions:
0	r0 = splat 0 (0)
loop:
1	    store32 ptr1 r0
2	    store32 ptr2 r0
3	    store32 ptr3 r0
4	    store32 ptr4 r0
Add program-too-large test using for loops without blocks. The fuzzer has discovered a bug in our program size-checking logic; for loops that immediately contain another for loop (with no block) were not counting the inner loop's iterations. This allowed it to exceed our maximum program-size threshold (and time out during SkVM compilation). This test demonstrates the issue. A followup will fix it.
