Timo Kreuzer 4e3c0529cf [RTL/x64] Fix RtlCaptureContext/RtlpRestoreContextInternal in kernel mode
According to tests, legacy fp state is not saved in kernel mode.
Also add an int 2c to the path that changes cs, as it should not be used and probably never will be.

RTL restrictions:

ExAllocatePool (and friends) must be used exclusively. RtlAllocateHeap (and friends) must NOT be used! ExAllocatePool (and friends) translate to RtlAllocateHeap (and friends) in ntdll\rtl\libsupp.c.

RtlEnterCriticalSection (and friends) must be used exclusively. ExAcquireFastMutex (and friends) must NOT be used! RtlEnterCriticalSection (and friends) translate to ExAcquireFastMutex (and friends) in ntoskrnl\rtl\libsupp.c. This means that RtlEnterCriticalSection (and friends) can NOT be used recursively in RTL. The reason for choosing RtlEnterCriticalSection (and friends) over ExAcquireFastMutex (and friends) is that the FAST_MUTEX struct is smaller than the RTL_CRITICAL_SECTION struct.
