Summary:
Sema::CheckCompletedCoroutineBody was growing unwieldy with building all of the substatements. Also, constructors for CoroutineBodyStmt had way too many parameters.
Instead, CoroutineBodyStmt now defines CtorArgs structure with all of the required construction parameters.
CheckCompleteCoroutineBody delegates construction of individual substatements to short functions one per each substatement.
Also, added a drive-by fix of initializing CoroutinePromise to nullptr in ScopeInfo.h.
And addressed the FIXME that wanted to tail allocate extra room at the end of the CoroutineBodyStmt to hold parameter move expressions. (The comment was longer that the code that implemented tail allocation).

classes.
MSVC actively uses unqualified lookup in dependent bases, lookup at the
instantiation point (non-dependent names may be resolved on things
declared later) etc. and all this stuff is the main cause of
incompatibility between clang and MSVC.
Clang tries to emulate MSVC behavior but it may fail in many cases.
clang could store lexed tokens for member functions definitions within
ClassTemplateDecl for later parsing during template instantiation.
It will allow resolving many possible issues with lookup in dependent
base classes and removing many already existing MSVC-specific
hacks/workarounds from the clang code.

their associated .cpp file.
Previous refactorings long long ago had split out the above categories
of classes from Stmt.h into their own header files, but failed to also
split the Stmt.cpp implementation file similarly. Do so for
readability's sake.
