"fix" PR4612, which is a crash on:
...
%0 = malloc [3758096384 x i32]
The "malloc" instruction doesn't support 64-bits correctly (see PR715),
and should be removed. Victor is actively working on fixing this, in
the meantime just don't crash.

Revert r75581: it causes massive breakage in the Ada
...
testsuite, due to exception handling not working
correctly. Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday. Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc. This is a
nasty flaw in the nightly testers. (On the other
hand the Ada testsuite links with the just built
libgcc).

Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address.
...
Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.

Switch the driver back to always using clang-cc by default (for C++, and
...
regardless of the architecture).
- This is a good default for development & testing; for example without this
any tests using 'clang' in the test suite will fail on PowerPC, since the
driver will avoid using clang.
- We don't want to actually ship something built this way, but that should be
handled via some sort of configuration file.
