bebe645914 Following a suggestion of Daniel Dunbar, stop people passing the name 
as the isSigned bool to CreateIntCast by having this resolve to a call
to a private method, rather than by using a gcc attribute.

f6d8788686 Fail less mysteriously; inform the user that their LLVM was not built with 
libffi support and that the interpreter can't call external functions without
it. Patch by Timo Juhani Lindfors! Fixes PR5466.

7fc73a45da When moving a block for table jumps, make sure the prior block terminator 
is analyzable so it can be updated. If it's not, be safe and don't move the
block.

fc21555ca5 Remove the optimizations that convert BRCOND and BR_CC into 
unconditional branches or fallthroghes. Instcombine/SimplifyCFG
should be simplifying branches with known conditions.

This fixes some problems caused by these transformations not
updating the MachineBasicBlock CFG.

d530046ed3 Set Rm bits of BX_RET to 0b1110 (R14); and set condition code bits of BRIND to 
0b1110 (ALways).  This is so that the disassembler decoder can distinguish among
BX_RET, BRIND, and BXr9.

by the recent FixedStackPseudoSourceValue-related changes, now that
the specific bug that affected it is fixed, in r88954.

9f05d972b7 Revert the test from r88984. It relies on being able to mmap 16GB of 
address space (though it only uses a small fraction of that), and the
buildbots disallow that.

Also add a comment to the Makefile's ulimit line warning future
developers that changing it won't work.

0f846dbb3e Make X86-64 in the Large model always emit 64-bit calls. 
The large code model is documented at
http://www.x86-64.org/documentation/abi.pdf and says that calls should
assume their target doesn't live within the 32-bit pc-relative offset
that fits in the call instruction.

To do this, we turn off the global-address->target-global-address
conversion in X86TargetLowering::LowerCall(). The first attempt at
this broke the lazy JIT because it can separate the movabs(imm->reg)
from the actual call instruction. The lazy JIT receives the address of
the movabs as a relocation and needs to record the return address from
the call; and then when that call happens, it needs to patch the
movabs with the newly-compiled target. We could thread the call
instruction into the relocation and record the movabs<->call mapping
explicitly, but that seems to require at least as much new
complication in the code generator as this change.

To fix this, we make lazy functions _always_ go through a call
stub. You'd think we'd only have to force lazy calls through a stub on
difficult platforms, but that turns out to break indirect calls
through a function pointer. The right fix for that is to distinguish
between calls and address-of operations on uncompiled functions, but
that's complex enough to leave for someone else to do.

Another attempt at this defined a new CALL64i pseudo-instruction,
which expanded to a 2-instruction sequence in the assembly output and
was special-cased in the X86CodeEmitter's emitInstruction()
function. That broke indirect calls in the same way as above.

This patch also removes a hack forcing Darwin to the small code model.
Without far-call-stubs, the small code model requires things of the
JITMemoryManager that the DefaultJITMemoryManager can't provide.

Thanks to echristo for lots of testing!

f3784a8781 Don't build examples by default, use BUILD_EXAMPLES=1 to build them. The only utility of this is testing that we keep the examples up to date, I will just make the buildbots run with this flag.
