Fix Rubinius.asm block, they're full expressions
Fix Rubinius.asm block, they're full expressions

Previously, .asm blocks were more like snippits. Now they're full
expressions, so they should leave a value on the stack, and the compiler
generates code to clean them up. If they cleanup themselves, then they
cause a stack underflow.
