a selector, the entry should be complete, containing everything introduced by
that module and all modules it imports.

Before writing out the method pool of a module, we sync up the out of date
selectors by pulling in methods for the selectors, from all modules it imports.

In ReadMethodPool, after pulling in the method pool entry for module A, this
lets us skip the modules that module A imports.

if we are parsing a template specialization.

This commit makes changes to clear the TemplateParamScope bit and set
the TemplateParamParent field of the current scope to null if a template
specialization is being parsed.

Before this commit, Sema::ActOnStartOfLambdaDefinition would check
whether the parent template scope had any decls to determine whether
or not a template specialization was being parsed. This wasn't correct
since it couldn't distinguish between a real template specialization and
a template defintion with an unnamed template parameter (only template
parameters with names are added to the scope's decl list). To fix the
bug, this commit changes the code to check the pointer to the parent
template scope rather than the decl list.

[OPENMP] Enable correct generation of runtime call when target directive is separated from teams directive by multiple curly brackets

http://reviews.llvm.org/D18474

This patch fixes a bug in code generation of the correct OpenMP runtime library call in presence of target and teams, when target is separated by teams with multiple curly brackets. The current implementation will not be able to see the teams directive inside target and issue a call to tgt_target instead of the correct one tgt_target_teams.

Usually these parameters are used solely to initialize the field in the
initializer list, and there is no real shadowing confusion.

There is a new warning under -Wshadow called
-Wshadow-field-in-constructor-modified. It attempts to find
modifications of such constructor parameters that probably intended to
modify the field.

It has some false negatives, though, so there is another warning group,
-Wshadow-field-in-constructor, which always warns on this special case.
For users who just want the old behavior and don't care about these fine
grained groups, we have a new warning group called -Wshadow-all that
activates everything.

Fixes PR16088.
