Bug in len() builtin

[drjdn]

The builtin len() function fails on the following:

gomacro> a := [...]int{1,2,3}
gomacro> a
[1 2 3]	// [3]int
gomacro> cap(a)
3	// int
gomacro> len(a)
runtime error: invalid memory address or nil pointer dereference

This is on an x86-64 Linux system running kernel 4.14.60. Doubt the system I'm running has much to do with this error but if so just let me know and I can provide further details.

Thanks,
Jason

The optimization that evaluates len() at compile time was incomplete. fixed in 0eb51bf
