Revert "Turn off extern templates for most uses."

Turning off explicit template instantiation leads to a pretty
significant build time and code size cost. We're better off dealing
with ABI incompatibility issues that come up in a less heavy handed
way.

This reverts commit r189610.

Get testsuite running on FreeBSD.

Add initial support for using LIT to run the tests on FreeBSD. 
More work may need to be done to add support for FreeBSD but this is a
good initial step.

Revert get testsuite running on FreeBSD.

There is a similar patch up for review. I'll submit my changes via that.

Readding FreeBSD support to lit.cfg. Patch from Pawel Worach.

Pawel has been using this patch on his buildbots for a while. This should
allow the testsuite to run on FreeBSD with libcxxrt.

[libcxx] Update the way the -std= flag is chosen by CMake and LibcxxTestFormat

Summary:
This patch does two things:
CMake Update:
  - Add compiler flag checks for -std=c++11 and -std=c++1y and remove check for -std=c++0x.
  - Add configuration option LIBCXX_ENABLE_CXX1Y to prevent/allow -std=c++1y from being chosen as the std version. LIBCXX_ENABLE_CXX1Y is set to OFF by default.
  - if LIBCXX_ENABLE_CXX1Y is enabled then set LIBCXX_STD_VERSION to c++1y and fail if the compiler does not support -std=c++1y
  - If c++1y is not enabled then use c++11 and fail if the compiler does not support c++11.

Lit Update:
  - Update lit.site.cfg.in to capture LIBCXX_STD_VERSION information as config.std.
  - Remove mentions of has_cxx0X configuration option.
  - Check for `--param std=X' passed to lit on the command line.
  - Choose the std for the tests either from command line parameter or (if it doesn't exist) the lit.site.cfg.

[libcxx] Add support for LLVM_USE_SANITIZER to libcxx when being built standalone and in-tree

Summary:
This patch adds support for LLVM_USE_SANITIZER when being built in-tree and standalone. 

This patch does the following things:
1. define the LLVM_USE_SANITIZER option to "" when being built standalone. This also helps show we support it.
2. Translate LLVM_USE_SANITIZER when standalone in a very similar way done in llvm/cmake/HandleLLVMOptions.cmake.
3. Add config.llvm_use_sanitizer to lit.site.cfg.in
4. Add code to translate config.llvm_use_sanitizer's value into the needed compile flags in lit.cfg.

Currently lit.cfg assumes that that the compiler supports '-fno-omit-frame-pointer' while CMakeLists.txt actually checks to see if its supported. We could pass this information to lit but I'm not sure its needed.

[libcxx] Add list of currently known buildbots to libc++ homepage

Summary:
Instead of having to update test results for different platforms it would be helpful to just supply links to buildbots that build+test libcxx.
For the FreeBSD bots Pawel Worach gave me the OK to link to them.

[libcxx] Add UNSUPPORTED tag to lit. It mirrors REQUIRES.

Summary:
This patch adds support for // UNSUPPORTED: feature. If an excluded feature is found in the list of available features then the test is marked unsupported.

I hope to use this to mark test unsupported if the fail with msan on asan. As well as tests that fail in particular standard modes.
