ab857f5e45 arm_dyncom_dec: Hide the decoding table from external view 
This isn't used externally anywhere (and really shouldn't be).

b37a850654 dyncom: Remove VFP_REG_ZERO 
Fixes two issues that will never happen:

1. There are cases when VFP_REG_ZERO will be non-zero, but these will
   never be encoutered in well behaved guest code (i.e. writing to D16).

2. If CONFIG_VFPv3 is defined, accessing VFP_REG_ZERO would be out of
   bounds.

a0874a7a68 Dyncom/VFP: Perform flush-to-zero on the second operand of vsub before sending it to vadd. 
Previously we were letting vadd flush the value to positive 0, but there are cases where this behavior is wrong, for example,

vsub: -0 - +0 = -0
vadd: -0 + +0 = +0

Now we'll flush the value to +0 inside vsub, and then negate it.

ba20dd9b61 gdbstub: Remove global variable from public interface 
Currently, this is only ever queried, so adding a function to check if the
server is enabled is more sensible.

If directly modifying this externally is ever desirable, it should be done
by adding a function to the interface, rather than exposing implementation
details directly.

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.
