This was meant to be easy, but I kept wondering if it was safe to remove the
inline call frame check in Arguments::tearOff(). The check was clearly dead
since the bit wasn't being set anywhere.
        
It turns out that the unwindCallFrame() function was relying on tearOff()
doing the right thing for inlined code, but it wasn't even passing it an
inline call frame. I fixed this by having unwindCallFrame() inlining check,
while also making sure that the code uses the right operand index for the
arguments register.

Don't store the "processing-instruction" string for PI tokens in the XPath parser

For PI tokens, the string is always going to be "processing-instruction", and it's never used so we don't need to save it.
