Richard Osborne e4cc98686a [XCore] Fix instruction selection for zext, mkmsk instructions. 
r182680 replaced CountLeadingZeros_32 with a template function
countLeadingZeros that relies on using the correct argument type to give
the right result. The type passed in the XCore backend after this
revision was incorrect in a couple of places.

Patch by Robert Lytton.

where the sign bit is implicit in the instruction
encoding.

This let us to remove some custom code that matched constant offsets
from globals at instruction selection time as a special addressing mode.

Richard Osborne f18d95f756 [XCore] The RRegs register class is a superset of GRRegs. 
At the time when the XCore backend was added there were some issues with
with overlapping register classes but these all seem to be fixed now.
Describing the register classes correctly allow us to get rid of a
codegen only instruction (LDAWSP_lru6_RRegs) and it means we can
disassemble ru6 instructions that use registers above r11.

Richard Osborne 9a228a13c6 Fix order of operands for crc8_l4r 
The order in which operands appear in the encoded instruction is different
to order in which they appear in assembly. This changes the XCore backend to
use the instruction encoding order.

Richard Osborne 3fb7395233 Add instruction encodings / disassembly support 3r instructions. 
It is not possible to distinguish 3r instructions from 2r / rus instructions
using only the fixed bits. Therefore if an instruction doesn't match the
2r / rus format try to decode it as a 3r instruction before returning Fail.

Jakob Stoklund Olesen ed6c0408fa Remove variable_ops from call instructions in most targets. 
Call instructions are no longer required to be variadic, and
variable_ops should only be used for instructions that encode a variable
number of arguments, like the ARM stm/ldm instructions.
