opcodes: add new sub-mnemonic disassembler style
When adding libopcodes disassembler styling support for AArch64, it
feels like the results would be improved by having a new sub-mnemonic
style. This will be used in cases like:
add w16, w7, w1, uxtb #2
^^^^----- Here
And:
cinc w0, w1, ne
^^----- Here
This commit just adds the new style, and prepares objdump to handle
the style. A later commit will add AArch64 styling, and will actually
make use of the style.
As this style is currently unused, there should be no user visible
changes after this commit.
