WASM fix orcus native exception handling (NEH)

Browse source 
While this fixes the build with --enable-wasm-exceptions, the
resulting binary generates an "indirect call signature mismatch",
which doesn't happen with the non-NEH build.

The Chrome DWARF backtrace points to CallbackTaskScheduling().
Further debugging reveals, it's actually the UpdateMinPeriod
call for the "desktop::Desktop m_firstRunTimer" Timer.
Disturbingly the debug dynamic_cast<Timer> at the start of the
job loop fails, and the fallback generic job output is
chosen, AKA:

info:vcl.schedule: 6516 0x3871618  i: 0 a: 1 p: 1 \
    desktop::Desktop m_firstRunTimer

m_firstRunTimer is a Timer member in the Desktop class, so this
looks like some memory corruption or toolchain problem.

The size difference is more then 10% and it's supposed to be
faster too. FWIW the optimized link time is still high and needs
32GB+ memory compared to the 13GB non-optimized memory usage.
