Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Kostya Serebryany d74d04a6c5 Add weak definitions of trace-cmp hooks to dfsan
Summary:
This allows to build and link the code with e.g.
-fsanitize=dataflow -fsanitize-coverage=trace-pc-guard,pc-table,func,trace-cmp
w/o providing (all) the definitions of trace-cmp hooks.

This is similar to dummy hooks provided by asan/ubsan/msan for the same purpose,
except that some of the hooks need to have the __dfsw_ prefix
since we need dfsan to replace them.

Dimitry Andric 66749021d4 Make check_custom_wrappers.sh work on FreeBSD
Summary:
When running the compiler-rt testsuite on FreeBSD (it didn't matter which version), I always got the same error result:

    FAILED: cd /home/dim/obj/llvm-234092-trunk-freebsd10-amd64-ninja-rel-1/projects/compiler-rt/lib && LLVM_CHECKOUT=/home/dim/src/llvm/trunk SILENT=1 TMPDIR= PYTHON_EXECUTABLE=/usr/local/bin/python2.7 COMPILER_RT=/home/dim/src/llvm/trunk/projects/compiler-rt /home/dim/src/llvm/trunk/projects/compiler-rt/lib/sanitizer_common/scripts/check_lint.sh
    The following differences between the implemented custom wrappers and the tests have been found:

After some investigation, it turns out to be due to the regex used for search test_ symbols in lib/dfsan/scripts/check_customer_wrappers.sh:

    grep -E "^\\s*test_.*\(\);" ${DFSAN_CUSTOM_TESTS}

This uses \s to search for whitespace at start of line, but support for \s was only introduced in GNU grep v2.5.4-112-gf979ca0, while both FreeBSD and OSX only have grep 2.5.1 (the last version released under GPLv2).

I propose to change \s into [[:space:]], which is the more portable notation.

Test Plan: Run regression tests, and see that they work now. :)
