Zebediah Figura 79c102d6be ntdll: Reserve space for the whole 64-bit YMM context in struct x86_thread_data. 
Fixes a regression introduced by 308a5e7c4d.

This was previously broken, but happened to work until the aforementioned
commit put the YMM state right at the end of a page.

Paul Gofman 8b8ddffa21 ntdll: Preserve syscall frame when calling async IO system APC. 
The frame can currently be reset from ws2_32.dll async IO callbacks
which are still in the user part and are calling 'syscall' functions.
If the user APC is processed after that during the same call to
server_select(), the call_user_apc_dispatcher() faults.
