Add a size alignment check to the .seh_stackalloc directive parser. Add a
more descriptive error message to the .seh_handler directive parser.
Add methods to the TargetAsmInfo struct in support of all this.

deficiencies exist:
- Works only if ABI is o32.
- Zero-sized structures cannot be passed.
- There is a lot of redundancy in generated code.

after checking for a GEP, so that it matches what GetUnderlyingObject
does. This fixes an obscure bug turned up by bugpoint in the testcase
for PR9931.

those lldb objects which implement the IsValid() method, let's change the rest of
the test suite to use the more compact truth value testing pattern (the Python way).

that the unevaluated subexpressions of &&, ||, and ? : are not
considered when determining whether the expression is a constant
expression. Also, turn the "used in its own initializer" warning into
a runtime-behavior warning, so that it doesn't fire when a variable is
used as part of an unevaluated subexpression of its own initializer.
Fixes PR9999.

through sugared types when testing for TagTypes. This was the actual
cause of the only false positive in Clang+LLVM.
Next evaluation will be over a much larger selection of code including
large amounts of open source code.

- Teach X86 cmov optimization to eliminate the cmov from ctlz, cttz extension
when the source of X86ISD::BSR / X86ISD::BSF is proven to be non-zero.

variable arguments in LowerCall and LowerFormalArguments. This should also fix
the bug in which handling of variable arguments is incorrect when the front-end
optimizes away unused fixed arguments.

issues and also add a test.
We should now handle defaulted members of templates properly. No
comment as to whether or not this also holds for templated functions,
but defaulting those is kind of insane.

can end up with an invalid path if the path resolves to something different
on the local machine. It is very important not to since remote debugging will
mention paths that might exist on the current machine (like
"/System/Library/Frameworks/CoreFoundation/CoreFoundation" which on the desktop
systems is a symlink to "/System/Library/Frameworks/CoreFoundation/Versions/A/CoreFoundation").
We will let the platform plug-ins resolve the paths in a later stage.

The general out-of-line case (including explicit instantiation mostly
works except that the definition is being lost somewhere between the AST
and CodeGen, so the definition is never emitted.
