Byte-code speedup [PATCH] |

The branch scratch/bytecode-speedup now contains a set of related improvements
to speed up the byte-code interpreter. If someone is allergic to Git, I could
post them as separate patches.
Performance is improved in many ways but is mostly focussed on making Elisp's
lamentably slow function calls faster, which should benefit a lot of code.
Operations on fixnums have also been sped up, as well as some data structure
access.
Equally importantly, the C stack requirements has shrunk meaning that users can
recurse deeper before getting a segfault. For example, bytecode is no longer
copied to a stack buffer for execution. I intend to carry this process further
in a set of follow-up patches, but the current changes are definitely good
enough on their own.
I have run a wide set of benchmarks; regressions are rare but obviously not all
code benefits equally. Most code becomes at least a little faster.
Unless there are good arguments not to, I'll merge it to master shortly.
