Fix QML Compiler crash

After commit 2afb54fb51091765f79548b0b057795bc3c6eb38,
Primitive::undefinedValue() uses setM() to clear out all bits.
Previously that code was #ifndef'ed out for the bootstrap build, but now
that we can do the correct boxing in host builds (as we know the pointer
size), we can re-enable setM() in bootstrap builds and fix this crash
that was a Q_UNREACHABLE() assertion.
