Simplify the computation of undefined symbols. Instead of walking
functions and initializers, just report the declarations present in
the module.
The motivation is to open the way for using the lazy module parsing,
which should speed up clients that just want a symbol list (nm, ar).
This is slightly less precise, but since both -strip-dead-prototypes
and -globaldce are part of the standard pipeline, this shouldn't
change the result for clang/dragonegg produced binaries.
Any decl in an IL file was also put there because a FE expected it
to be necessary, so this should not be a problem for "-O0 -emit-llvm".
As a sanity check, I have bootstrapped clang on linux and built
firefox on both linux and darwin. A clang bootstrap on darwin
with LTO fails with or without this patch because, ironically,
the linker doesn't like the combination of dead_strip and LTO
when building libLTO.so :-)

Hoist spills when the same value is known to be in less loopy sibling registers.
Stack slot real estate is virtually free compared to registers, so it is
advantageous to spill earlier even though the same value is now kept in both a
register and a stack slot.
Also eliminate redundant spills by extending the stack slot live range
underneath reloaded registers.
This can trigger a dead code elimination, removing copies and even reloads that
were only feeding spills.

The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byte
rather than an int. Thankfully, this only causes LLVM to miss optimizations, not
generate incorrect code.
This just fixes the zext at the return. We still insert an i32 ZextAssert when
reading a function's arguments, but it is followed by a truncate and another i8
ZextAssert so it is not optimized.

1. The ARM Darwin *r9 call instructions were pseudo-ized recently.
Modify the ARMDisassemblerCore.cpp file to accomodate the change.

imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate)
