Clean up the minor mess I caused with removing iterator.h. I shall take care of 80-col violations and the FIXME later. (Thanks goodness that I live in another continent, so the monkeypox did not strike me :-)

calls into a function and if the calls bring in arrays, try to merge
them together to reduce stack size.  For example, in the testcase
we'd previously end up with 4 allocas, now we end up with 2 allocas.

As described in the comments, this is not really the ideal solution
to this problem, but it is surprisingly effective.  For example, on
176.gcc, we end up eliminating 67 arrays at "gccas" time and another
24 at "llvm-ld" time.

One piece of concern that I didn't look into: at -O0 -g with
forced inlining this will almost certainly result in worse debug
info.  I think this is acceptable though given that this is a case
of "debugging optimized code", and we don't want debug info to
prevent the optimizer from doing things anyway.

When checking whether one declaration context encloses another, make sure to look at the primary contexts. Thanks to Eli for the test case

In ActOnCXXTypeConstructExpr, check that the type is complete and non-abstract before creating any expressions. This assures that any templates are instantiated if necessary.

Despite common miscomceptions, iterator.h is alive and well. It broke the build
bots for several hours. And yet no one bothered to look at them.

Gabor and Doug, please review your changes and make sure that they actually
build before resubmitting them.

CodeGen will be doing particularly interesting CFG modifications.

Simplify 'Environment' to contain only one map from 'const Stmt*' to SVals, greatly simplifying the logic of the analyzer in many places.  We now only distinguish between block-level expressions and subexpressions in Environment::RemoveDeadBindings and GRState pretty-printing.

This fixes potential spurious (though probably otherwise
harmless) poising of unused memory, and fixes the
associated valgrind error.

moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.
