Add initial tests for reading register sets from core dumps. This
includes a C++ program to write registers and dump core, resulting core
dumps for Linux, FreeBSD and NetBSD, and the tests to verify them.
The tests are split into generic part, verifying user-specified register
values, and coredump-specific tests that verify memory addresses that
differ for every dump.
At this moment, all platforms support GPRs and FPRs up to XMM for amd64
target. The i386 target does not work on NetBSD at all, and is missing
FPRs entirely on FreeBSD.
This is a work-in-progress PR. TODO:
1. Verifying core dumps against 32-bit kernel (there are made with -m32
currently).
2. Reduce the size of FreeBSD core dumps (can we use compression here?).
