After some experiments I discovered that clang doesn't support static
initialization of flexible array members in full, so restored this paragraph in
"GCC extensions not implemented yet" list.

#pragma weak, global register variables and static initialization of flexible
array members are supported now, so they are removed from "GCC extensions not
implemented yet" list.

This builds on the support being added to LLVM to import and export
registries from DLLs.  This will allow us to pick up the registry
entries added in the DLL's copy of FrontendPluginRegistry.

This will allow us to use plugins on Windows using:
$ clang-cl -Xclang -load -Xclang plugin.dll \
           -Xclang -add-plugin -Xclang foo

Summary:
MSVC's driver accepts all unknown arguments but warns about them.  clang
by default rejects all unknown arguments.  This causes issues
specifically with build systems such as autoconf which liberally pass
things such as $LDFLAGS to the compiler and expect everything to work.
This patch teaches clang-cl to ignore unknown driver arguments.

Provide separate visitor templates for the three hierarchies, and also
the `FullSValVisitor' class, which is a union of all three visitors.

Additionally, add a particular example visitor, `SValExplainer', in order to
test the visitor templates. This visitor is capable of explaining the SVal,
SymExpr, or MemRegion in a natural language.

Compared to the reverted r257605, this fixes the test that used to fail
on some triples, and fixes build failure under -fmodules.

Adds driver options named -glldb and -gsce to mean -g plus tuning for
lldb and SCE debuggers respectively; the existing -ggdb option does
the same for gdb. Existing options -ggdb0, -ggdb1 etc. unpack into
-ggdb -g<N>.  (There will not be -glldb<N> or -gsce<N> options.) The
tuning gets a target-specific default in the driver, and is passed
into cc1 with the new -debugger-tuning option.

As fallout, fixes where '-gsplit-dwarf -g0' would ignore the -g0 part
on Linux.
