Erik Pilkington 94d2ac7160 [demangler] Use an AST to represent demangled names
The demangler now demangles by producing an AST, then traverses that
AST to produce a demangled name. This is done for performance reasons,
now the demangler doesn't manuiplate std::strings, which hurt
performance and caused string operations to be inlined into the
parser, leading to large code size and stack usage.

Eric Fiselier 84800d999c Remove dependancy on __refstring header; use local copy instead.
This patch removes the dependancy on libc++'s __refstring header,
which was only a header in the first place so that libc++abi could
build library code using it, and not because libc++ needed it in
the headers.

This patch allows libc++ to stop shipping <__refstring> publicaly
at the cost of duplicating it across projects. Ideally libc++abi
would always require the libc++ sources when building, but that's
a separate discussion I plan to start on the mailing lists shortly.

Saleem Abdulrasool cf0e48ca01 build: use cmake to pass -std=c++11
Rather than manually checking for support for the spelling of the C++
standard, indicate to CMake that we require that the compiler support
C++11 and that we compile without the GNU extensions.  This simplifies
the flags handling in libc++abi itself by relying on CMake to translate
the flag and add it as appropriate.

Saleem Abdulrasool e3568b4b3d build: use POSITION_INDEPENDENT_CODE CMake property
Use the POSITION_INDEPENDENT_CODE target property to indicate that we
should be building with -fPIC or the equivalent flag based on the
toolchain that we are using.  This makes the check more portable and
simplifies the flags management.  Because we don't want this setting to
propagate in the case of an in-tree build, set the property on the
targets we construct explicitly rather than setting
CMAKE_POSITION_INDEPENDENT_CODE to ON globally.

Eric Fiselier 27db230ab0 Remove requirement for libunwind sources. Patch by Shiz.
As per r241993, libunwind_ext.h is not used anymore, and thus only the public libunwind includes are needed.
This eases distro packaging efforts and removes an unneeded requirement for out-of-tree building.

Erik Pilkington a34ea7583f [demangler] Fix a exponential string copying bug
The problem was that if base_name() was called from a context without
an actual base name, it could gulp up the entire string, which can
result in recursive duplications. The fix is to be more strict as to
what qualifies as a base name.

Tamas Berghammer 8bc9b88a24 __cxa_demangle: Fix constructor cv qualifier handling
Summary:
Previously if we parsed a constructor then we set parsed_ctor_dtor_cv
to true and never reseted it. This causes issue when a template argument
references a constructor (e.g. type of lambda defined inside a
constructor) as we will have the parsed_ctor_dtor_cv flag set what will
cause issues when parsing later arguments.

Akira Hatanaka 0c1016a337 [libcxxabi] Align unwindHeader on a double-word boundary.
r276215 made a change to annotate _Unwind_Exception with attribute
"aligned" so that an exception object following field __cxa_exception
is sufficiently aligned. This fix hasn't been incorporated to unwind.h
on Darwin since it is an ABI breaking change.

Instead of annotating struct _Unwind_Exception with the attribute, this
commit annotates field unwindHeader of __cxa_exception. This ensures the
exception object is sufficiently aligned without breaking the ABI.

This recommits r302978 and r302981, which were reverted in r303016
because a libcxx test was failing on an AArch64 bot. I also modified the
libcxxabi test case to check the alignment of the pointer returned by
__cxa_allocate_exception rather than compiling the test with -O1 and
checking whether it segfaults.

libc++abi can't depend on libc++, so disable extern templates in libc++

I consider it more appropriate to do at the cmake level (since none of
libc++abi's source files can use libc++ extern templates).

I also think the _LIBCPP_NO_EXCEPTIONS in cxa_demangle.cpp is
suspicious, but I'm doing one thing at a time.
