eb00bea1ff backend/x64/exception_handler_posix: Fix signal stack memory leak in SigHandler 
std::malloc was being called inside SigHandler's constructor without a
std::free. This doesn't really matter as SigHandler is used as a
singleton and the OS will reclaim that memory. That said, properly
freeing memory keeps -fsanitize=address quiet.

13367a7efd A64: Match A32 page_table code 
Here we increase the similarity between the A64 and A32 front-ends in terms of their
page_table handling code. In this commit, we:

* Reserve and use r14 as a register to store the page_table pointer.
* Align the code to be more similar in structure.
* Add a conf member to A32EmitContext.
* Remove scratch argument from EmitVAddrLookup.

8b3bc92bce backend/x64: Reduce conversions required for cpsr_nzcv 
The guest program often accesses the NZCV flags directly much less
often than we need to use them for jumps and other such uses.

Therefore, we store our flags in cpsr_nzcv in a x64-friendly format.

This allows for a reduction in conditional jump related code.
