When we vectorize across multiple basic blocks we may vectorize PHINodes that create a cycle. We already break the cycle on phi-nodes, but arithmetic operations are still uplicated. This patch adds code that checks if the operation that we are vectorizing was vectorized during the visit of the operands and uses this value if it can.

[stackprotector] Changed isNoopBitcast/sameNoopInput to take TargetLoweringBase instead of TargetLowering.

Both functions only use functionality from TargetLoweringBase.

This reverts commit r186866.

This breaks the build and the original author Guillaume Papin
<guillaume.papin@epitech.eu> asked me to revert so he could look at it more with
revane.

The headers in the compiler's own resource include directory are
system headers, which means we don't stat() them eagerly when loading
a module. Use module.map as a proxy for these headers and the compiler
itself. Fixes <rdar://problem/13856838>.

Recommit r186813: More Intel syntax alias fixes. With the addition of suppressing some of the aliases from being emitted by the asm printer.

Instantiate RegisterContextCore... based on getOS() instead of with
compile-time #ifdef-ery.

The assert()s here are unfortunate, but better than crashing with no
explanation.  (This would previously happen for an unsupported
architecture, anyhow.)

We should add an equivalent OS and architecture test to
ProcessElfCore::DoLoadCore() and cleanly report the error to the user.

 Use the function attributes to pass along the stack protector buffer size.

 Now that we have robust function attributes, don't use a command line option to
 specify the stack protecto buffer size.

On FreeBSD I see that Arch, Vendor, OS, and Environment are unchanged
after this call (for x86_64, at least), and core debugging works without
it.

If we need to restore it we should be able to switch on
arch.GetTriple.getOS() instead of a compile-time #ifdef.

Thanks to Daniel Malea for testing on Linux.

There already have two "dead" functions, initialize{IPO|IPA}, defined for 
similar purpose. I decide not to call these two functions for two reasons:
  o. they don't cover all LTO passes (which will soon be separated into IPO 
     and post-IPO passes)
  o. We have not yet figured out the right passes and the ordering for IPO 
     and post-IPO stages, meaning this change is only for the time being.

Since LTO passes are registered, we are now able to print IR before and 
after particular point.

For OSX users:
--------------
  "...-Wl,-mllvm -Wl,-print-after=<pass-name>" will print IR after the
  specified pass.

For Other UNIX with GNU gold linker:
------------------------------------
  "-Wl,-plugin-opt=-print-after=<pass-name>" should work.
  (NOTE: no need for "-Wl,-mllvm")

  Strip "-Wl," if flags are fed directly to linker instead of clang/clang++.
