This allows us to drop dependency on NASM and build the test image
with GCC only. Adds support for x86_64, too.

At least GCC defines the symbol "i386" to 1 to signal the target
platform. We need to use "i386" as an undefined symbol in order to
correctly include risu_reginfo_i386.h from risu.h. Add an -U option to
the build command to make sure the symbol remains undefined.

Otherwise changes to reginfo don't cause the whole thing to be
re-built causing much confusion when bisecting.

This can cause much confusion when you have been building in your
source tree. I've added a distclean so we don't unexpectedly drop the
config for normal make clean invocations.

This uses the magic of zlib's gzread/write interface to wrap the
tracefile in compression. The code changes are tiny. I spent more time
messing about with the configure/linker stuff to auto-detect bits.
As you need decent multi-arch support or a correctly setup cross
toolchain we fall back if we can't compile with zlib. This
unfortunately needs some #ifdef hackery around the zlib bits in
risu.c.

send_register_info() is now essentially the same code for all
target CPUs, so move it into reginfo.c rather than having
duplicated code.

For x86 the ucontext.h only provides the #defines for register indexes
if _GNU_SOURCE is enabled; enable it.
As part of this, split our CFLAGS into:
* CFLAGS: can be set by the user, defaults to -g
* EXTRA_CFLAGS: set by the user, additional to CFLAGS
* ALL_CFLAGS: the above, plus flags we must have in order
to build correctly (or otherwise don't want the user to disable)

Add support for building outside the source tree, by running configure
from the build directory:
mkdir build
cd build
../configure
make

This will dump any risu.bin files to the risu.asm files which are so
useful for working through stuff. Of course you can run an individual
make target by running:
make simd_copy.risu.asm

put the struct reginfo and its methods in a separate module.
This also addresses the problem with the memcmp
being used directly on the struct without the memset 0.

adjust some types to be able to compile successfully on 64 bit.
To make it cleanly, add a configure step to check for the
appropriate types to use.
