229e4523f2 Expand Op0Mask by one bit in preparation for the PadLock prefixes.
Define most shift masks incrementally to reduce the redundant
hard-coding. Introduce new shift for the VEX flags to replace the
magic constant 32 in various places.

539d8d8a72 Assorted bugfixes in object file handling:
- Adds support for sniffing PE/COFF files on win32 (.exe and .dll)
   which are COFF files that have an MS-DOS compatibility stub on
   the front of them.

 - Fixes a bug in the COFFObjectFile's support for the Microsoft COFF
   extension for long symbol names, wherein it was attempting to parse
   the leading '/' in an extended symbol name reference as part of the
   integer offset.

 - Fixes bugs in COFFObjectFile and ELFObjectFile wherein section
   and symbol iterators were being returned with uninitialized bytes;
   the type DataRefImpl is a union between 2 32-bit words (d.a and d.b)
   and a single intptr_t word (p). Only p was being initialized, so in
   32-bit builds the result would be iterators with random upper 32-bit
   words in their DataRefImpls. This caused random failures when
   seeking around in object files.

71ad2c9eda PR9446: RecursivelyDeleteTriviallyDeadInstructions can delete the instruction
after the given instruction; make sure to handle that case correctly.
(It's difficult to trigger; the included testcase involves a dead 
block, but I don't think that's a requirement.) 

While I'm here, get rid of the unnecessary warning about
SimplifyInstructionsInBlock, since it should work correctly as far as I know.

f5b75932b8 While SimplifyDemandedBits constant folds this, we can't rely on it here.
It's possible to craft an input that hits the recursion limits in a way
that SimplifyDemandedBits doesn't simplify the icmp but ComputeMaskedBits
can infer which bits are zero.

No test case as it depends on too many other things. Fixes PR9609.

0b7bc77e30 Handle changing of LLVM_ENABLE_FFI.
If someone first configure build with LLVM_ENABLE_FFI=1 and then turn it
off, the build will fail in lib/ExecutionEngine/Interpreter because
Interpreter will try still to #include <ffi/ffi.h>, but there are no
include_directories(${FFI_INCLUDE_DIR}) now.

This patch unset()'s HAVE_FFI_H and HAVE_FFI_FFI_H from cache file if
LLVM_ENABLE_FFI=0. This forces CMake to update config.h.

all the instruction have:

    let Inst{31-27} = 0b1110; // non-predicated

Before, the ARM decoder was confusing:

> 0x40 0xf3 0xb8 0x80

as:

Opcode=16 Name=ADCSSrs Format=ARM_FORMAT_DPSOREGFRM(5)

-------------------------------------------------------------------------------------------------

	adcs	pc, r8, r0, asr #6

since the cond field for ADCSSrs is a wild card, and so is ADCrs, with the ADCSSrs having Inst{20} as '1'.

Now, the AR decoder behaves correctly:

5337fabdc4 Tweaks to the icmp+sext-to-shifts optimization to address Frits' comments:

- Add an assert to make sure a case that would lead to a miscompilation is
  folded away earlier.
