The major win of this is that the code is simpler and they
print on the same line as the instruction again:
movl %eax, 96(%esp) ## 4-byte Spill
movl 96(%esp), %eax ## 4-byte Reload
cmpl 92(%esp), %eax ## 4-byte Folded Reload
jl LBB7_86

Enhance the x86 backend to show the hex values of immediates in
comments when they are large. For example:
movl $1072693248, 4(%esp) ## imm = 0x3FF00000

into MachineInstr. Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the
codebase.

Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly. Move testcase
to new directory.
Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.

cast instead of reinterpret_cast, fixing PR6243. Apparently
reinterpret_cast and I aren't getting along today.

Document that MCExpr::Div, Mod, and the comparison operators are all
signed operators.
Document that the comparison operators' results are target-dependent.
Document that the behavior of shr is target-dependent.

cast needs to adjust for a vtable pointer when going from base to
derived type (when the base doesn't have a vtable but the
derived type does).

This time it's for real! I am going to hook this up in the frontends as well.
The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.
We need some experiments to determine if that is the right thing to do.

llc.cpp also defined these flags, meaning that when I linked all of LLVM's
libraries into a single shared library, llc crashed on startup with duplicate
flag definitions. This patch passes them through the EngineBuilder into
JIT::selectTarget().

Instruction selection for X86 now can choose an instruction
sequence that will fit any address of any symbol, no matter
the pointer width. X86-64 uses a mov+call-via-reg sequence
for this.

a lot of things with int64_t offsets.

1-argument ExecutionEngine::create(Module*) ambiguous with the signature that
used to be ExecutionEngine::create(ModuleProvider*, defaulted_params). Fixed

There is still a ton of work left. Instructions are not being encoded
yet apparently.
