40077055cf arch-vega: Fix disassembly for two dword VOPC 
Calling opSelectorToRegSym in the disassembly for VOPC when there is a
second dword (SDWA, DPP, or Literal) causes a panic as those registers
do not have a string symbol. This is fixed by checking for a second
dword before printing similar to how VOP1, VOP2, SOP1, etc. function.

This patch is revamping/simplifying the access permission logic in the
ArmMMU (ArmMMU::s1PermBits64) by matching more closely the Arm
architecture reference manual pseudocode.

It also fixes VHE access permission: previous version was not
considering the EL2&0 translation regime.
Now EL2&0 is handled correctly through the new hasUnprivRegime method

590719a383 arch-vega: explain when op encoder ignores src reg 
Previously b40b361bee added support for the Vega operand encoder.  As
part of this, it made sure to check for the S_GETPC_B64 instruction,
which appears to be the only instruction in the Vega ISA that does not
use the source register.  However, at the time the commit used magic
numbers without comment, which can be difficult for users to interpret.

To resolve this, this commit adds a comment to explain where the magic
numbers come from (Table 58 in the Vega ISA manual).

00008b725c arch-vega: some Vega instructions don't use dest reg 
Some of the Vega scalar instructions (S_SETPC_B64, S_RFE_B64,
S_CBRANCH_JOIN, and S_SET_GPR_IDX_IDX) do not use the SDST scalar
destination register.  However, Vega's operand encoding function for the
SOP1 instruction type's class assumed all instructions used the
destination register, which results in an assert failure for these
instructions.

To resolve this, this commit updates the Vega SOP1 operand encoder to
ignore the destination register for these specific instructions.

b836e6a495 arch-x86: Stop using (read|set)IntReg. 
These accessors just translate a RegIndex x into a RegId(IntRegClass, x)
and then does (get|set)Reg. Instead, we can just do (get|set)Reg
directly, since all the integer register named constants are just RegIds
now.

Now that op_idx is trivial to calculate (just src_reg_idx or
dest_reg_idx), there's no need to have the indirection and extra
mechanism to funnel a precalculated value around.
