the size of pointer).

to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around.  Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch.  Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

 - Currently also enables the behavior that allows silent redefinition
   of types in system headers. Conceptually these are separate but I
   didn't feel it was worth two options (or changing LangOptions).

If you're on some other platform, the correct definition for this macro 
would be appreciated; to find the correct definition, just run the 
following command:

difference from generic x86 is the defines.  The rest is non-trivial to 
implement.

I'm not planning on adding any more targets myself; if there are any 
targets anyone is currently using that are missing, feel free to add 
them, or ask me to add them.

This concludes the work I'm planning for the TargetInfo 
implementations at the moment; all the other issues with TargetInfo require
some API changes, and I haven't really thought it through.  Some of the
remaining issues: allowing targets to define size_t and wchar_t properly,
adding some sort of __builtin_type_info intrinsic so we can finish clang's 
limits.h and float.h and get rid of a massive number of macro 
definitions, allowing target-specific command-line options, allowing
target-specific defaults for certain command-line options like
-fms-extensions, exposing vector alignment outside of the description 
string, exposing endianness outside of the description string, allowing 
targets to expose special bit-field layout requirements, exposing some 
sort of custom hook for call generation in CodeGen, and adding CPU 
selection to control defines like __SSE__.

This approach allows adding OS-specific targets/defines/etc. without 
completely breaking unknown subtargets.  No new subtargets yet, although 
I plan to add x86-Linux soon.  Others can add targets that they use as 
needed; adding a new subtarget takes very little code.

Also does some fixups for description strings; a lot of them were 
unspecified.  I think all the ones I added are correct, but 
they're unverified; corrections are welcome.

cleaned it up a bit, including fixing the definition of va_list; this
shouldn't break anything, but anyone using Sparc should watch for 
regressions.

visible effects, but this will significantly reduce the amount of 
boilerplate code necessary to add subtargets.

If this looks okay, I'll do the rest of the processors (PPC, Sparc, ARM) 
soon.
