Adjust Qiling to comply with latest changed in Unicorn 2.1.2

[elicn]

[Merge only after Unicorn 2.1.2 is officially released]

Highlights:

• Introduced co-processor register accessors to AArch32 and AArch64 (ql.arch.cpr)
• Replaced deprecated pseudo registers with cpr definitions to be used with the new accessors
• Separated x86 64-bit only registers from the rest as Unicorn became less tolerant to accessing unsupported registers
• SSE instructions are no longer supported on the default Intel CPU model. x86 tests that use SSE instructions are now set to use Intel Haswell CPU model to make sure SSE is supported
• Various opportunistic styling and annotation fixes

Fixes: #1495, #1329

The next release will be 2.1.2 and it seems only Separated x86 64-bit only registers from the rest as Unicorn became less tolerant to accessing unsupported registers needs 2.2?

Ah, no, that's probably my mistake. I'll fix the title accordingly.
