add_public_tablegen_target adds *CommonTableGen to LLVM_COMMON_DEPENDS.
LLVM_COMMON_DEPENDS affects add_llvm_library (and other add_target stuff) within its scope.

There was exactly one caller using this API right, the others were relying on
specific behavior of the default implementation. Since it's too hard to use it
right just remove it and standardize on the default behavior.

This let us to remove some custom code that matched constant offsets
from globals at instruction selection time as a special addressing mode.
No intended functionality change.

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.

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.

Currently there is no instruction encoding info and
XCoreDisassembler::getInstruction() always returns Fail. I intend to add
instruction encodings and tests in follow on commits.
