a bit nicer for people who pass lots of extra arguments to calls by
selecting them all instead of just the first one:
arg-duplicate.c:13:13: error: too many arguments to function
f3 (1, 1, 2, 3, 4); // expected-error {{too many arguments to function}}
^~~~~~~
This implements test/Sema/arg-duplicate.c, thanks to Neil for pointing
out this crash.

1) fix a crash on test/Sema/default.c by making
sure that the switch scope is non-null.
2) if there is an error sema'ing a default or case stmt,
make sure to return the substmt up, so that the error
recovery code has more acurate info to continue with.

llvm intrinsics in llvm-gcc-4.2. This is because
get_pointer_alignment bails out: it relies on TER
to compute accurate alignment information.

SourceManager::getInstantiationLoc. With this change, every token
expanded from a macro doesn't get its own MacroID. :)
This reduces # macro IDs in carbon.h from 16805 to 9197

fileid/offset pair, it now contains a bit discriminating between
mapped locations and file locations. This separates the tables for
macros and files in SourceManager, and allows better separation of
concepts in the rest of the compiler. This allows us to have *many*
macro instantiations before running out of 'addressing space'.
This is also more efficient, because testing whether something is a
macro expansion is now a bit test instead of a table lookup (which
also used to require having a srcmgr around, now it doesn't).
This is fully functional, but there are several refinements and
optimizations left.

code that cross integer / floating point domains (e.g. generate pxor / pand for
logical ops on floating point value, movdqa to load / store floating point SSE
values). Given that, it's better to use movaps instead of movdqa and movups
instead of movdqu. They have the same latency but the "aps" variants are one
byte shorter.
If the domain crossing problem is a real performance issue, then we will have to
fix it with dynamic programming based isel.

Change the keywords for the zext and sext parameter attributes to be
zeroext and signext so they don't conflict with the keywords for the
instructions of the same name. This gets around the ambiguity.

We still need to do sematic analysis (and implement initializers), however this
should complete the parsing & ast building for compound literals.
