* We failed to invalidate entries if there are no patches required for a location descriptor.
* Bug in A64 hashing code (rbx instead of rbp).
* Bug in A32 and A64 lookup code (inconsistent choice of key: PC vs IR::LocationDescriptor).
* Test case added.
* Provide reason for halting and atomically update this.
* Allow user to specify a halt reason and return this information on halt.
* Check if halt was requested prior to starting execution.
In MSVC, having files with identical filenames will result into massive slowdowns when compiling.
The approach I have taken to resolve this is renaming the identically named files in frontend/(A32, A64) to (a32, a64)_filename.cpp/h
We might want to allocate different sizes for each of them.
e.g. for the unsafe fastmem approach without bounds checking.
Or for using the full 48bit adress range (with mirrors) by allocating our real arena as close to 1<<47 as possible.
