This is a small addition to arithmetic operations that improves
expressiveness of the language.

Additionally, allow more than two operands to !con, !add, !and, !or
in the same way as is already allowed for !listconcat and !strconcat.

Convert the operand to int if possible, i.e. if the value is properly
initialized. (I suppose there is further room for improvement here to also
peform the shift if the uninitialized bits are shifted out.)
With this little change we can now compute the scaling factor for compressed
displacement with pure tablegen code in the X86 backend. This is useful
because both the X86-disassembler-specific part of tablegen and the assembler
need this and TD is the natural sharing place.
The patch also adds the missing documentation for the shift and add operator.

In historical reason, tblgen is not strictly required to be free from memory leaks.
For now, I mark them as XFAIL, they could be fixed, though.
