Fix crash on Windows

Follow-up to commit 67b09aef34ff7997808e04194cdb92273ec76f14 about changing
the masm back-end to support returning the VM::Value in eax:edx instead
of through an invisible first pointer parameter: If the address of where
to store the return value is passed on the stack, it is the callee's
responsibility to take that one off the stack. We do that by emulating the
ret(n) instruction. However on Windows we don't want to do that because
we use the eax:edx register pair, so the correct #ifdef to use here is
RETURN_VALUE_IN_REGISTER, not ARGUMENTS_IN_REGISTERS.

Fix occasional crashes on x86 due to alignment issues

As it turns out, the stack is required to be aligned to 16 bytes on x86. This
patch makes sure of that.

This also rewrites the parameter handling for function calls to be much simpler
and also faster by replacing the use of individual push instructions for stack
arguments with one stack pointer subtraction for all arguments followed by
shorter moves (poke) for each argument.
