headers, which use C++0x generalized initializer lists. Per PR7069, it
appears that the only use is as the return type of a function, so this
commit enables this extension just in that narrow case. If it's enough
for libstdc++ 4.5, or if it can be trivially extended to work with
libstdc++ 4.5, we'll keep it. Otherwise, or if this breaks anything,
we'll revert and wait for the real feature.

Profiling showed that 'CheckImplicitConversions' was very slow because of the call to getSpellingLoc().  On 'aes.c'
in the LLVM test suite, this function was consuming 7.4% of -fsyntax-only time.  This change fixes this issue
by delaying the check that the warning would be issued within a system macro by as long as possible.  The
main negative of this change is now the logic for this check is done in multiple places in this function instead
of just in one place up front.

When doing reachability analysis for warnings issued under DiagRuntimeBehavior, don't construct a ParentMap or CFGStmtMap.
Instead, create a small set of Stmt* -> CFGBlock* mappings during CFG construction for only the statements we care about
relating to the diagnostics we want to check for reachability.

Rework interaction between AnalysisContext and CFG::BuildOptions to keep a BuildOptions object around instead of keeping a copy of the flags.

Moreover, change AnalysisContext to use an OwningPtr for created analysis objects instead
of directly managing them.

Finally, add a 'forcedBlkExprs' entry to CFG::BuildOptions that will be used by the
CFGBuilder to force specific expressions to be block-level expressions.

simplify the logic of initializing function parameters so that we don't need
both a variable declaration and a type in FunctionArgList.  This also means
that we need to propagate the CGFunctionInfo down in a lot of places rather
than recalculating it from the FAL.  There's more we can do to eliminate
redundancy here, and I've left FIXMEs behind to do it.
