Jordan Rose 07a7ed80cb [analyzer] Don't strip CXXBaseObjectRegions when checking dynamic_casts.
...and /do/ strip CXXBaseObjectRegions when casting to a virtual base class.

This allows us to enforce the invariant that a CXXBaseObjectRegion can always
provide an offset for its base region if its base region has a known class
type, by only allowing virtual bases and direct non-virtual bases to form
CXXBaseObjectRegions.

This does mean some slight problems for our modeling of dynamic_cast, which
needs to be resolved by finding a path from the current region to the class
we're trying to cast to.

Jason Molenda 4d04d477d9 When emulating instructions that read from memory,
return 0x0 as the read value instead of uninitialized
stack data so we get consistent behavior from the
emulator.

Jakob Stoklund Olesen 702bcc3bcf Remove the TII::scheduleTwoAddrSource() hook.
It never does anything when running 'make check', and it get's in the
way of updating live intervals in 2-addr.

The hook was originally added to help form IT blocks in Thumb2 code
before register allocation, but the pass ordering has changed since
then, and we run if-conversion after register allocation now.

When the MI scheduler is enabled, there will be no less than two
schedulers between 2-addr and Thumb2ITBlockPass, so this hook is
unlikely to help anything.

Chad Rosier 65a8e0b69f [ms-inline asm] Have patchMSAsmStrings() return a vector or AsmStrings.
The AsmParser expects a single asm instruction, but valid ms-style inline asm
statements may contain  multiple instructions.

This happens with asm blocks

__asm {
  mov ebx, eax
  mov ecx, ebx
}

or when multiple asm statements are adjacent to one another

__asm mov ebx, eax
__asm mov ecx, ebx

and

__asm mov ebx, eax __asm mov ecx, ebx

Currently, asm blocks are not properly handled.
