This reverts commit r220665.

llvm-svn: 220667

r220665 makes configure or CMake to set HAVE_CXXABI_H on FreeBSD 10.0.
We don't need this ugly ifdef condition anymore.

llvm-svn: 220666

On FreeBSD 10.0, size_t needs to be defined before including cxxabi.h.
Currenty HAVE_CXXABI_H is not defined on FreeBSD because of that reason.
This patch teaches cmake and configure how to include it.

All of these test fixups are prep work for when llgs is
running with llgs for local process debugging, where these
tests fail without the ptracer lock-down suppression.

llvm-svn: 220655

Similar to previous fix, this augments the test inferior to
immediately indicate it may be ptraced by any Linux process
when the appropriate symbols are defined.

This seems to indicate we need to fix our lldb attach logic to
catch when an attach fails, and trigger an appropriate error
instead of the current behavior of hanging indefinitely.

Hopefully this fixes the bug that was introduced in r220642, and not-quite-fixed
in r220649.

llvm-svn: 220653

We used to always vectorize (slp and loop vectorize) in the LTO pass pipeline.

r220345 changed it so that we used the PassManager's fields 'LoopVectorize' and
'SLPVectorize' out of the desire to be able to disable vectorization using the
cl::opt flags 'vectorize-loops'/'slp-vectorize' which the before mentioned
fields default to.
Unfortunately, this turns off vectorization because those fields
default to false.
This commit adds flags to the LTO library to disable lto vectorization which
reconciles the desire to optionally disable vectorization during LTO and
the desired behavior of defaulting to enabled vectorization.

We really want tools to set PassManager flags directly to enable/disable
vectorization and not go the route via cl::opt flags *in*
PassManagerBuilder.cpp.

HostThreadWindows::Join() did not call the Reset as is done by
the HostThreadPosix::Join(). As a result, future call to 
IsJoinable() can fail.

Committed as obvious.

Similar to a recent test I fixed for gdb-remote attach scenarios, this
fix is for Linux kernels, such as Ubuntu's stock setup on 11.04-ish and
later, where ptrace starts requiring a ptracer to be an ancestor of the
inferior to be ptraced.  This change checks for Linux and the ptrace-related
flags.  If they're found, it tries to switch on the "allow any ptracer" mode
for the inferior as the first statements in the program.  It's a best-effort
solution - if the prctl call fails, the failure is ignored, and probably will
lead to the test failing.

The ptrace security behavior can be modified system-wide, but is outside the
scope of the test to address.  Hence I went with this particular solution.

Apparently unique_ptr'ifying NodeMetadata exposed an issue in VS where it
occasionally tries to synthesize copy constructors instead of moves. Hopefully
explicitly deleting the copy constructor and defining the move constructor will
fix this.

No functional change. This just brings things more in-line with coding
standards, and makes ValuePool's functionality clearer (it's not tied to pooling
costs, and we may want to use it to hold other things in the future).

introduce a BufferedStackTrace class, which owns this array.

Summary:
This change splits __sanitizer::StackTrace class into a lightweight
__sanitizer::StackTrace, which doesn't own array of PCs, and BufferedStackTrace,
which owns it. This would allow us to simplify the interface of StackDepot,
and eventually merge __sanitizer::StackTrace with __tsan::StackTrace.

Test Plan: regression test suite.
