Change the interface to expose the new information and deal with the enormous fallout.
Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications.
Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support.

simplify the logic of initializing function parameters so that we don't need
both a variable declaration and a type in FunctionArgList.  This also means
that we need to propagate the CGFunctionInfo down in a lot of places rather
than recalculating it from the FAL.  There's more we can do to eliminate
redundancy here, and I've left FIXMEs behind to do it.

clobber with the 'y' constraint. Otherwise, we get the wrong return type and an

CodeGenFunction::GenerateBlockFunction() should initialize DebugInfo just like CodeGenFunction::GenerateCode()

llvm-svn: 127174

DebugInfo can be enabled or disabled at function level (e.g. using an attribute). However, at module level it is determined by command line option and the state of command line option does not change during compilation. Make this layering explicit and fix accidental cases where the code generator was checking whether module has debug info enabled instead of checking whether debug info is enabled for this function or not.

For example, here user would expect to stop at line 22, even if A's constructor leads to a call through CXXDefaultArgExpr.

we weren't treating the new-initializer as being conditionally executed,
