Chandler Carruth 210c77b38c Add -whole-archive around the ASan runtime archive in the link command.
This ensures that even though it comes first, we pick up its .o files.
Note that if we can use this (or something similar / equivalent) on
other platforms, we could potentially remove
ReplaceOperatorsNewAndDelete from the ASan runtimes.

We should probably do something similar for TSan and MSan as well.

Matt Beaumont-Gay 35439dff76 Currently, with -fsanitize=address, the driver appends libclang_rt.asan.a to
the link command. This all works fine when the driver is also responsible for
adding -lstdc++ to the link command. But, if -lstdc++ (or libstdc++.a, etc) is
passed explicitly to the driver, the ASan runtime will appear in the link
command after the standard library, leading to multiple-definition errors for
the global 'operator new' and 'operator delete'. Fix this in a painfully
simple way, by inserting libclang_rt.asan.a at the start of the link command
instead of the end.

If we need to do something more clever, we can walk the link command looking
for something that resembles libstdc++ and insert libclang_rt.asan.a as late
as possible, but the simple solution works for now.

Eric Christopher 0499778517 Make sure that we put the rest of the sanitizer libraries on the link line
before libstdc++ like we do with ubsan.

Richard Smith 52be619c84 Add -fsanitize=<sanitizers> argument to driver and frontend, and add
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the
various UBSan checks to be enabled and disabled separately. Right now, the
different modes can't be combined, but the intention is that combining UBSan
and the other sanitizers will be permitted in the near future.

Currently, the UBSan checks will all be enabled if any of them is; that will be
fixed by the next patch.

Evgeniy Stepanov 763671edeb Android standalone toolchain support.
This change adds detection of C++ headers and libraries paths when
building with the standalone toolchain from Android NDK. They are in a
slightly unusual place.
