David Majnemer 149e603132 [MS ABI] Workaround corner-case bug in the ABI for operator delete 
MSVC only genreates array cookies if the class has a destructor.  This
is problematic when having to call T::operator delete[](void *, size_t)
because the second argument's argument is impossible to synthesize
correctly if the class has no destructor (because there will be no array
cookie).

Instead, MSVC passes the size of the class.  Do the same, for
compatibility, instead of crashing.

This fixes PR23990.

Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag. 
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Bill Wendling 706469b453 Add more of the command line options as attribute flags. 
These can be easily queried by the back-end.

Anna Zaks 0f424b029b Revert "Add more attributes from the command line to functions." 
This reverts commit 176009.

The commit is a likely cause of several buildbot failures.

Bill Wendling 87869db5f5 Add more attributes from the command line to functions. 
This is an ongoing process. Any command line option which a back-end cares about
should be added here.

function attributes.

John McCall 7f0245d930 Remove some not-very-stable assumptions from this testcase.

John McCall b91cd6687c Refactor the C++ ABI code a little bit to take advantage of 
what I'm going to treat as basically universal properties of
array-cookie code.  Implement MS array cookies on top of that.
Based on a patch by Timur Iskhodzhanov!
