This was always the intended behavior: when --embedded-variant is not
passed, we should assume "Default". What actually happened in this
case was that we'd initialize to nullptr. This CL adds the missing
nullptr check.

This changes gcmole's bootstrapping script so that it always creates
binaries that link libstdc++ statically (both plugin and Clang) and do
not link against unneeded libraries (only Clang). For deployment of
gcmole on our infrastructure, it is much easier to have fewer external
dependencies.

Compiling without -fno-exceptions causes compilation errors, this
CL fixes that.

The reason for the compilation error is a mismatch of "V8_NOEXCEPT"

copy/move constructors, but present on base::Optional for defaulted
ones.

This is a false positive of a potential evaluation order problem flagged
by the newest version of gcmole. While this is strictly speaking safe,
it is not statically known that the default argument of the fourth
parameter to {AbsoluteAndNot} is a nullptr and hence not a stale raw
reference. Since this is the only false positive of this kind in the
code base, I would vote to just avoid it by sequencing the operations.

Consolidates all the work into a single TFS builtin (CreateHTML)
called by all these functions. Reduces the builtin size by
about half.

Since the new Objects were introduced, we can no longer cast integers to
and Object pointer and call methods on them in gdb (due to how gdb's
expression evaluator deals with temporaries). So, we add a new helper
method to our gdbinit, "$job", which takes an address and returns an
Object that is now exists in real (stack) memory.

This should have no effect unless the embedder uses an old version
of the standard library with missing overloads of <math.h> functions,
which causes such functions to perform implicit conversion to double.
In such cases, the CL removes the implicit conversion.

Compilation only stores whether an error has been found, but not the
exact error or it's location. This is generated by running a validation
pass once all wire bytes have been received.
This unifies error messages by removing one more location where we
generate compilation error messages, and makes it deterministic because
a) we always report the error in the first failing function, and
b) if names are present, the error message will always contain the
   function name.

Piggybacking of splitting heap setup, this change adds a shared
read-only heap and a flag to enable it.

Also makes CallOnce use std::function instead of a raw function
pointer so the CL can use lambdas with CallOnce.
