ed6ca58058 A32: Implement ASIMD VCEQ, VCGE, VCGT, VCLE, VCLT with zero 
Fairly self-explanatory, we can leverage the existing IR functions for
the purpose of these instructions.

In the integer case, we can just insert function pointers
into an array and index it, given all comparison primitives exist
already for the integer side of things.

This may emit a vmrs *, fpscr instruction.
This results in fuzz failures due to slight inaccuracies in fpscr emulation.

94d0d33e02 Fix single stepping for certain instructions 
Several issues:
1. Several terminal instructions did not stop at the end of a single-step block
2. x64 backend for the A32 frontend sometimes polluted upper_location_descriptor with the single-stepping flag

We also introduce the enable_optimizations parameter to the A32 frontend.

b50114ae70 A64/fuzz_with_unicorn: Avoid repeated unnecessary library calls in RunTestInstance() 
Repeatedly retrieving the vectors and registers from unicorn involves
copying the entire set of registers and vectors by value instead of
simply retrieving a reference to them. Instead, we can just do the work
once and print out the values.

While we're at it, also make our bracing consistent.
