Hans Wennborg 9125b08b52 Update tests in preparation for using the MS ABI for Win32 targets
In preparation for making the Win32 triple imply MS ABI mode,
make all tests pass in this mode, or make them use the Itanium
mode explicitly.

Jordan Rose 3437669ca9 [analyzer] Type information from C++ new expressions is perfect.
This improves our handling of dynamic_cast and devirtualization for
objects allocated by 'new'.

Anna Zaks 6bab4ef4e8 [analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".
The idea is to eventually place all analyzer options under
"analyzer-config". In addition, this lays the ground for introduction of
a high-level analyzer mode option, which will influence the
default setting for IPAMode.

Jordan Rose 2010d437f9 [analyzer] Re-add reinterpret_cast virtual call test case from r163644.
We mostly just don't want to crash analyzing this test case; it's likely
the code found here will actually crash if compiled and run.

Jordan Rose 99c6c2b4e2 Revert "[analyzer] Use the static type for a virtual call if the dynamic type is worse."
Using the static type may be inconsistent with later calls. We should just
report that there is no inlining definition available if the static type is
better than the dynamic type. See next commit.

This reverts r163644 / 19d5886d1704e24282c86217b09d5c6d35ba604d.

Jordan Rose e35fdeb330 [analyzer] Use the static type for a virtual call if the dynamic type is worse.
reinterpret_cast does not provide any of the usual type information that
static_cast or dynamic_cast provide -- only the new type. This can get us
in a situation where the dynamic type info for an object is actually a
superclass of the static type, which does not match what CodeGen does at all.
In these cases, just fall back to the static type as the best possible type
for devirtualization.

Should fix the crashes on our internal buildbot.

Jordan Rose 5132aaeb04 [analyzer] Don't inline dynamic-dispatch methods unless -analyzer-ipa=dynamic.
Previously we were checking -analyzer-ipa=dynamic-bifurcate only, and
unconditionally inlining everything else that had an available definition,
even under -analyzer-ipa=inlining (but not under -analyzer-ipa=none).
