Thank you very much for this patch and all the legal difficulties that
went with it.

We don't commit patches this big in one swoop, so I had to split it up.
The order in which they are meant to be applied is:

  sm-codegen.diff
  sm-beautify.diff
  sm-small-fixes.diff
  sm-hwcap.diff
  sm-better-code.diff
  sm-icache.diff
  sm-tls.diff

The changes in sm-superfluous.diff seem, well, superfluous to me :-)

When contributing patches, please also use our coding style, especially
regarding indentation and where to put spaces:

I've fixed all of that in your code as far as it caught my eye.

Paolo: Please review the patches, especially the hwcap, icache and TLS
stuff.  I can't say much about those, but everything else looks fine,
and everything works (runtime and corlib regressions, tested on
PPC64/linux and PPC32/darwin).

Mark
