1604115c5a Move --march, --mcpu, and --mattr from JIT/TargetSelect.cpp to lli.cpp. 
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().

a44be8b7f3 Disable external stubs for X86-32 and X86-64 
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.

be6cf8cfb0 Change the argument to getIntegerSCEV to be an int64_t, rather 
than int. This will make it more convenient for LSR, which does
a lot of things with int64_t offsets.

disassembly library that provide access to
instruction information, and fixed ambiguous

92abe5abcc r94686 changed all ModuleProvider parameters to Modules, which made the 
1-argument ExecutionEngine::create(Module*) ambiguous with the signature that
used to be ExecutionEngine::create(ModuleProvider*, defaulted_params).  Fixed
by removing the 1-argument create().  Fixes PR6221.

of const ones.  non-const ones aren't very useful, because you can't

78f57ac8dc Hook up -filetype=obj through the MachO streamer. Here's a demo: 
$ cat t.ll 
@g = global i32 42
$ llc t.ll -o t.o -filetype=obj
$ nm t.o
00000000 D _g

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

643f2f9bc4 refactor code so that LLVMTargetMachine creates the asmstreamer and 
mccontext instead of having AsmPrinter do it.  This allows other 
types of MCStreamer's to be passed in.

Now the only use of the ELF writer is the JIT, which won't be
easy to fix in the short term. :( :(

0b2c2769ba Generalize target-independent folding rules for sizeof to handle more 
cases, and implement target-independent folding rules for alignof and
offsetof. Also, reassociate reassociative operators when it leads to
more folding.

Generalize ScalarEvolution's isOffsetOf to recognize offsetof on
arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr
to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.

Make the target-dependent folder promote GEP array indices to
pointer-sized integers, to make implicit casting explicit and exposed
to subsequent folding.

And add a bunch of testcases for this new functionality, and a bunch
of related existing functionality.
