This patch adds a new set of JIT APIs to LLVM. The aim of these new APIs is to
cleanly support a wider range of JIT use cases in LLVM, and encourage the
development and contribution of re-usable infrastructure for LLVM JIT use-cases.

These APIs are intended to live alongside the MCJIT APIs, and should not affect
existing clients.

Included in this patch:

1) New headers in include/llvm/ExecutionEngine/Orc that provide a set of
   components for building JIT infrastructure.
   Implementation code for these headers lives in lib/ExecutionEngine/Orc.

2) A prototype re-implementation of MCJIT (OrcMCJITReplacement) built out of the
   new components.

3) Minor changes to RTDyldMemoryManager needed to support the new components.
   These changes should not impact existing clients.

4) A new flag for lli, -use-orcmcjit, which will cause lli to use the
   OrcMCJITReplacement class as its underlying execution engine, rather than
   MCJIT itself.

Tests to follow shortly.

Special thanks to Michael Ilseman, Pete Cooper, David Blaikie, Eric Christopher,
Justin Bogner, and Jim Grosbach for extensive feedback and discussion.

SimplifyCFG currently does this transformation, but I'm planning to remove that
to allow other passes, such as this one, to exploit the unreachable default.

This patch takes care to keep track of what case values are unreachable even
after the transformation, allowing for more efficient lowering.

In llvm-mode, with electric-pair-mode turned on, typing a literal '['
would print out '[[', and '(' would print a '(('. This was a very
annoying bug caused by overzealous syntax-table entries: the parens are
already part of the '(' and ')' class by default. Fix this.

While at it, notice that i32, i64, i1 etc. are not font-locked despite a
clear intent to do so. The issue is that regexp-opt doesn't accept
regular expressions. So, spell out the common literal integers with
different widths.

We did't properly mark all of an AnnotatedLine's children as finalized
and thus would reformat the same tokens in different branches of #if/#else
sequences leading to invalid replacements.

[compiler-rt] Ensure AsanInitFromRtl is called from a static initializer on OS X by using ASAN_DYNAMIC=1

The idea is to ensure that the ASan runtime gets initialized early (i.e.
before other initializers/constructors) even when DYLD_INSERT_LIBRARIES
is not used. In that case, the interceptors are not installed (on OS X,
DYLD_INSERT_LIBRARIES is required for interceptors to work), and therefore
ASan gets currently initialized quite late -- from the main executable's
module initializer. The following issues are a consequence of this:

  https://code.google.com/p/address-sanitizer/issues/detail?id=363
  https://code.google.com/p/address-sanitizer/issues/detail?id=357

Both of them are fixed with this patch.

The interceptor of ioctl is using a non-standard prototype:

  INTERCEPTOR(int, ioctl, int d, unsigned request, void *arg)

At least on OS X, the request argument should be unsigned long and not 
just unsigned, and also instead of the last argument (arg), the function
should be accepting a variable number of arguments, so the prototype
should be:

  int ioctl(int fildes, unsigned long request, ...);

We can still keep using `unsigned` internally to save space, because we
know that all possible values of `request` will fit into it.

This mostly reverts commit r222062 and replaces it with a new enum. At
some point this enum will grow at least for other MSVC EH personalities.

Also beefs up the way we were sniffing the personality function.
Previously we would emit the Itanium LSDA despite using
__C_specific_handler.

The driver currently accepts but ignores the -fno-signed-zeros flag. 
This patch passes the flag through and enables 'nsz' fast-math-flag 
generation in IR.

The existing OpenCL flag for the same functionality is made into an
alias here. It may be removed in a subsequent patch.

The shrink_to_fit() method is more readable and more effective than
the copy and swap trick to reduce the capacity of a shrinkable container.
Note that, the shrink_to_fit() method is only available in C++11 and up.

Example:

std::vector<int>(v).swap(v); will be replaced with v.shrink_to_fit();

Summary:
We used to silently ignore any empty .module's and we used to give an error saying that we found
an "unexpected token at start of statement" when the value of the option wasn't an identifier (e.g. if it was a number).

We now give an error saying that we "expected .module option identifier" in both of those cases.

I also fixed the other tests in mips-abi-bad.s, which all seemed to be broken.
