Stefan Weil 1b7621ad99 w64: Fix TCG helper functions with 5 arguments TCG uses 6 registers for function arguments on 64 bit Linux hosts, but only 4 registers on W64 hosts. Commit `2999a0b200` increased the number of arguments for some important helper functions from 4 to 5 which triggered a bug for W64 hosts: QEMU aborts when executing helper_lcall_real in the guest's BIOS because function tcg_target_get_call_iarg_regs_count always returned 6. As W64 has only 4 registers for arguments, the 5th argument must be passed on the stack using a correct stack offset.

Stefan Weil 1b7621ad99 w64: Fix TCG helper functions with 5 arguments

TCG uses 6 registers for function arguments on 64 bit Linux hosts,
but only 4 registers on W64 hosts.

Commit 2999a0b200 increased the number
of arguments for some important helper functions from 4 to 5
which triggered a bug for W64 hosts: QEMU aborts when executing
helper_lcall_real in the guest's BIOS because function
tcg_target_get_call_iarg_regs_count always returned 6.

As W64 has only 4 registers for arguments, the 5th argument must be
passed on the stack using a correct stack offset.
