Add execute-inline/range instruction.

Like "execute-inline", this is an instruction generated by dexopt that
replaces a method invoke instruction.  It's useful for small, frequently
called methods in the core libs.

As with execute-inline, we allow at most 4 arguments, but with /range
we're no longer limited to the low 16 registers.

Also: marked execute-inline as being able to throw an exception.

Needed: native x86 implementation; support in JIT.

For bug 2268232.
