93a3714816
ARM: Move the templates for predicated instructions into a separate file.
...
This allows the templates to all be available at the same time before any of
the formats, etc. This breaks an artificial circular dependence.

Gabe Black
79b288f7b5
ARM: Force the condition code for 16 bit thumb instructions to be unconditional.
...
Before, because 16 bit thumb instructions didn't set the upper 16 bits of the
ExtMachInst, that field would be interpretted as "equals".

ARM: Add a .w to the disassembly of 32 bit thumb instructions.
...
This isn't technically correct since the .w should only be added if there are
32 and 16 bit encodings, but always having it always is better than never
having it.

style: clean up ruby's Set class
...
Further cleanup should probably be done to make this class be non-Ruby
specific and put it in src/base.
There are probably several cases where this class is used, std::bitset
could be used instead.
