de460a4881 Pull in r227115 from upstream clang trunk (by Ben Langmuir):
Fix assert instantiating string init of static variable

  ... when the variable's type is a typedef of a ConstantArrayType. Just
  look through the typedef (and any other sugar).  We only use the
  constant array type here to get the element count.

This fixes an assertion failure when building the games/redeclipse port.

be01698709 Add FREEBSD-Xlist files for llvm, clang and lldb.
These are generated, and not "optimized" in any way, since I am not
entirely sure of the syntax or format of this type of file.  Feel free
to suggest ways of shortening these lists.

The general idea is the same for all three files, though:
* Get rid of upstream build infrastructure (CMakeLists, Makefiles, etc)
* Delete tests, tools and utilities we don't want or use (including
  samples)
* Remove various bits of upstream metadata files that we don't want or
  use (.arcconfig, .gitignore, etc)

Allows Clang to use LLVM's fixes-x18 option

  This patch allows clang to have llvm reserve the x18
  platform register on AArch64. FreeBSD will use this in the kernel for
  per-cpu data but has no need to reserve this register in userland so
  will need this flag to reserve it.

  This uses llvm r226664 to allow this register to be reserved.

Implement a new -fstandalone-debug option. rdar://problem/15685848
  It controls everything that -flimit-debug-info used to, plus the

  alias to -fstandalone-debug and vice versa.

  Standalone is the default on Darwin until dtrace is updated to work with
  non-standalone debug info (rdar://problem/15758808).

  because NoStandaloneDebugInfo sounded even more confusing.

f785676f2a Upgrade our copy of llvm/clang to 3.4 release. This version supports
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3.  The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

  In the following code:

  If 'A::sz' gets value below in the translation unit, the array in
  instantiation can turn into constant size array.

To enable them, set WITH_GCC and WITH_GNUCXX in src.conf.
Make clang default to using libc++ on FreeBSD 10.
Bumped __FreeBSD_version for the change.

GCC is still enabled on PC98, because the PC98 bootloader requires GCC to build
(or, at least, hard-codes the use of gcc into its build).

Thanks to everyone who helped make the ports tree ready for this (and bapt
for coordinating them all).  Also to imp for reviewing this and working on the
