ActOnMemberReferenceExpr, ActOnDestructorReferenceExpr (both of them),
ActOnOverloadedOperatorReferenceExpr,
ActOnConversionOperatorReferenceExpr, and
ActOnMemberTemplateIdReferenceExpr into a single, new action
ActOnMemberAccessExpr that does the same thing more cleanly (and can
keep more source-location information).

declarators are parsed primarily within a single function (at least for
these cases).  Remove some excess diagnostics arising during parse failures.

functions that don't have local linkage.  Basically, we need to be more
careful about propagating argument information to functions whose results
we aren't tracking.  This fixes a miscompilation of 
LLVMCConfigurationEmitter.cpp when built with an llvm-gcc that has ipsccp
enabled.

yet another copy of the unqualified-id parsing code.

Also, use UnqualifiedId to simplify the Action interface for building
id-expressions. ActOnIdentifierExpr, ActOnCXXOperatorFunctionIdExpr,
ActOnCXXConversionFunctionExpr, and ActOnTemplateIdExpr have all been
removed in favor of the new ActOnIdExpression action.

Split it to two checkers, one for undefined size, 
the other for zero size, so that we don't need to query the size
when emitting the bug report.

This makes both logical sense (see below) and increases the
number of functions marked readnone/readonly by about 1-2%
in practice.  The number of functions marked nocapture goes
up by about 5-10%.  The reason it makes sense is shown by
the following example: if you run -functionattrs -inline on
it, then no attributes are assigned.  But if you instead run
-inline -functionattrs then @f is marked readnone because the
simplifications produced by the inliner eliminate the store.

@x = external global i32

define void @w(i1 %b) {
        br i1 %b, label %write, label %return
write:
        store i32 1, i32 *@x
        br label %return
return:
        ret void
}

define void @f() {
        call void @w(i1 0)
        ret void
}

Move 'static inline' functions GetNullarySelector() and GetUnarySelector() from CFRefCount.cpp to ASTContext.h.  These functions are likely to be generally useful.
