commands except the last one, instead redirect the stderr to a temporary
file. This sidesteps a potential deadlocking issue.

Add a magic LLVM_DISABLE_CRT_DEBUG environment variable which we check in RegisterHandler and use to disable the Win32 crash dialogs. These are a major blocker to any kind of automated testing.

Also, tweak the 'lit' test runner to set this variable unconditionally.

Fix PR5024. LiveVariables::FindLastPartialDef should return a set of sub-registers that were defined by the last partial def, not just a single sub-register.

Switch DIDescriptor to use a TrackingVH. - This makes it much safer to work with debug info, since it was extraordinarily easy to have dangling pointers thanks to MDNode uniquing.

llvm-svn: 82507

This is designed for tracking a value even when it might move (like WeakVH), but it is an error to delete the referenced value (unlike WeakVH0. TrackingVH is templated like AssertingVH on the tracked Value subclass, it is an error to RAUW a tracked value to an incompatible type.

For implementation reasons the latter error is only diagnosed on accesses to a mis-RAUWed TrackingVH, because we don't want a virtual interface in a templated class.

The former error is also only diagnosed on access, so that clients are allowed to delete a tracked value, as long as they don't use it. This makes it easier for the client to reason about destruction.

Block.h/Block_private.h headers, since clients won't know what to
set. These are moved into runtime.c as appropriate

2) Use cmake checks for CAS builtins, instead of guessing based on GCC
#defines (which aren't set by clang and llvm-gcc anyway)

3) "#pragma mark" isn't supported by FSF gcc, so "#if 0" it out. It
should still show up in IDEs that support it

4) Fix some compiler warnings. GCC 4.3.3 seems super strict about
%p. function pointers can't be cast to void * either.

5) Avoid a warning for apple_versioning.c that "ISO C does not allow
empty files"

%S0<def> = EXTRACT_SUBREG %Q0<kill>, 1
to
%S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>

Implicit_def does not *read* any register so the operand should be marked "implicit". The missing "implicit" marker on the operand is wrong, but it doesn't actually break anything.

Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.
