PCH patch

[Geoffrey Keating]

[Forgot to attach the actual patch!]

Shortly after Mark makes the branch, I'll merge the PCH branch to 
mainline with something like this patch.

The PCH branch has been open for testing for some time now, and I got 
positive status reports (or at least, they sounded positive) for 
x86-linux, ia64-linux, x86-mingw.  I have also tested it myself on 
powerpc-darwin.

This particular patch has been bootstrapped & tested on powerpc-darwin, 
and I'm running an additional check on powerpc-eabisim.

There are some known test failures with the new patch, but they aren't 
regressions (in fact, they only affect debugging information when a PCH 
is used).  I also have some reports that PCH doesn't fully work on all 
platforms, this is to be expected, hopefully when the patch is in the 
mainline those who work on these platforms will be able to improve the 
situation.

The patch is 400K, a little too big to send uncompressed, so here it is 
compressed.
