   now).

 - Despite being a hack, its actually good enough to work over all of 403.gcc

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 :-)

Implement a new optimization in the inliner: if inlining multiple
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.

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.

now that include/llvm/ADT/iterator.h.in is not attempted to be built, its prerequisite can go away too

Simplify.

eliminate references to ADT/iterator.h

Make this into a static method.

Fix bad length argument to substr calls.  Apparently I'm the first one to
attempt more than 2 constraints on an instruction.

llvm-mc/Mach-O: Unique sections properly, so we don't get duplicate text
sections, etc.
 - The quick and dirty way, just clone the TargetLoweringObjectFile
   code. Eventually this should be shared... somehow.

llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.
 - I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).

Rework getPersonalityIndex slightly - 0 is now a valid and not-NULL
personality function.

nobody includes llvm/ADT/iterator.h any more,
so get rid of this monstrosity. iterator.h.in is scheduled for deletion in my working copy,
but I wait till I see that configure gets regenerated, as it depends on it. I'll commit
then.
There are still some AC_* tests in the configure.ac dealing with iterators, those can
be zapped probably too.

If we're emitting additional CIEs due to personality functions
don't emit the default one. Explicitly check for the NULL
CIE later.

Allocate the module provider in the Kaleidoscope code on the heap, not the stack, so that it can be properly deleted.  Also update the tutorial with the new code.  This fixes PR4762, hopefully better than the last time.

Remove all the LLVM_COMPACTIFY_SENTINELS-related macro magic as discussed with Chris on IRC. Anybody wanting to debug sentinel dereferencing problems must revert this patch and perform the indicated modifications.
