Include function return type in JSON AST dumps.

[rokups]

Summary

For some reason return type was not included. Even though it is present
in full type dump, it is not good enough as C++ types can get quite
complex. Besides there is no way to get a desugared version of the type
from function type string. Patch uses "returnType" json key, just like
ObjCMethodDecl dumper. I also updated tests. If anything is missing -
please let me know.

[rokups]

This seems to not be good enough, however. Somehow desugared version of type is not added anywhere.

[Temtaime]

Merge it, please. I badly need this field.

Hey @Temtaime,
Until we can rely on this i opted in for poor man's workaround - splitting type/qualType field at the first ( and using first part. I realize it is not reliable and will break when function pointers are used, but since they arent in my project that is an acceptable short term workaround.

   attributeOnlyIfTrue("modulePrivate", FD->isModulePrivate());
   attributeOnlyIfTrue("isBitfield", FD->isBitField());
   attributeOnlyIfTrue("hasInClassInitializer", FD->hasInClassInitializer());
 }
 
 void JSONNodeDumper::VisitFunctionDecl(const FunctionDecl *FD) {
   VisitNamedDecl(FD);
   JOS.attribute("type", createQualType(FD->getType()));
+  JOS.attribute("returnType", createQualType(FD->getReturnType()));
   StorageClass SC = FD->getStorageClass();
   if (SC != SC_None)
     JOS.attribute("storageClass", VarDecl::getStorageClassSpecifierString(SC));
