prints:

getelementptr (int* %A, int -1)

as: "(A) - 4" instead of "(A) + 18446744073709551612", which makes the
assembler much happier.

This fixes test/Regression/CodeGen/X86/2005-02-14-IllegalAssembler.ll,
and Benchmarks/Prolangs-C/cdecl with LLC on X86.

both cases they are looking for non-external variables/functions that do
not have internal linkage. Using "!isExternal()" is a little more
understandable than "hasInitializer()"

Otherwise, clients who call ParseAllFunctionBodies will attempt to parse
the function bodies twice, which is (uh) very very bad (tm).

This fixes gccld on python.

external reference with an internal reference.  This shrinks the libpython.a
symbol table from 126302 to 19770 bytes.

This patch reverts this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050131/023830.html

... which was an attempted fix for this problem.  Unfortunately, that patch
caused test/Regression/Transforms/IndVarsSimplify/exit_value_tests.llx to fail
and slightly castrated the entire analysis.  This patch fixes it right.

This patch is dedicated to jeffc, for making me deal with this.  :)

so, if you beat on it, you too can talk emacs into having a sane indenting policy...  Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
