Automatically and centrally detect C++11-mode based on how CIFactory.cpp is compiled; turn on cling's LangOpt.CPlusPlus11 accordingly.
No need to rely on ROOT's config flag anymore.

Replace all occurrences of strlen(x) == 0 with !x[0] which is far cheaper for long strings.

Simplify some of the patches by reverting some of the changed llvm / clang files to the original ones.

Parser::Scope versus Sema::DeclContext are now checked for cross-vailidity.
Emit the TU-transaction explicitly instead of relying on a first transaction.
The typename extraction now takes a stream instead of a string to write to.
The llvm::Linker has much reduced functionality; use llvm::sys::Path instead to find dynamic libraries.

Repair support for std::bitset.  It has no iterator and we can not
access the element by address, so we need to treat it the same way
we treat the associative container (cache the input into an array
of bool and use the 'feed' function.

the callbacks must be triggered for those, too.
As they are not part of a transaction (think "module") they are now sent to the deserialization listener.
This can be removed once the modules work.

Set the state of the transaction to Committing before the static init - which might trigger more decls even though CodeGen has been run over the decls.

Forward DeclCollector::HandleInterestingDecl() to DeclCollector::HandleTopLevelDecl() for decls from the AST reader / from headers describing libraries.

Empty transactions must be passed to TCling; they trigger the sending of deserialized decls to ROOT/Meta.

Don't start TCling's artificial TU Transaction if the transaction coming in is empty - we need a decl to get the ASTContext.

Swap the deserialized decls before handling them in TCling, such that nested calls don't see the same decls again.

Add the following 'merge' modes:

    'M'        final value will be the maximum
    'm'        final value will be the minimum
    'f'        final value will be the first encountered
    'l'        final value will be the last encountered

Defined also a new bit 'kIsConst' which is set if all the 'merged'
values are found to be the same; a new method 'Bool_t IsConst() const'
is provided to quickly test constancy.

Should provide a solution for the requirements raised in Savannah bug
#95957 and Savannah patch #5550.

Combine all code into one string, then *parse* that: no need to declare for modules as CodeGen must not be run, else we will have duplicate static symbols, in the library and codegened by declare().
Complain even if the method count differs between cling and meta.
Steal the collection of modified classes from TCling to avoid recursive changes to it.
Correct the flag "new declaration is from AST file".

The issue is that sometimes we don't have a begun transaction. This can happen
mostly in cases when the code doesn't come from text representation but:
  * From lookup, where template is being instantiated
  * From a PCH/PCM, where a decl was deserialized.

This patch solves the first case: When we do findScope we have to instantiate
the declaration if needed.
Every time there is a chance that generated code's declarations can be orphaned,
we have to explicitly push a transaction so that we can keep the integrity.
