ff506b0375 vm/x86: support extended fpu state transfer 
Extend Genode's vCPU FPU state and adjust all users to copy
at most FPU data they actually support.

2e92b7ae32 nova: enable FPU AVX support 
Add extended FPU state detection and handling (via xsave and friends) to the
kernel, which has to store/load more FPU state (~512 -> 2k++) during context
switching of threads. Additional the referenced nova branch contains various
optimization during VM destruction and cross core IPC resource caching.

This FPU work is based upon upstream NOVA kernel and Hedron commits.

99667de35b nova: limit assertions during early boot 
Turn some of the current assertions into warnings/error messages and
continue boot. Print the messages as soon as core_log is initialized,
so that on live/release systems (Sculpt OS) it may be inspected later on.

eaadc6aad6 nova: support to run on e-core only SOCs 
The code to group together SMT threads of one CPU and to move P-Core to
the beginning of Genode's affinity-space, did not consider to run on
SOCs with only E-Core CPUs.

Re-structure the code to support e-Core only SOCs.

Additionally, provide a fallback mapping in case of CPU id reordering problems.
Track faulty re-mapping and delay the reporting until core_log is initialized,
so that the warnings is visible to consumers, e.g. on Sculpt OS.

5c27993884 nova: transfer guest fpu state via utcb 
instead via the hardware registers of the FPU. On Genode all components and
so VMMs are built such, that the compiler may generate optimized code by
using the FPU at any time. We had to make sure to save the
FPU state as early as possible before the VMM component touches the FPU,
to avoid corrupting & losing guest FPU state. This caused headache again
and again. To avoid the uncertainty, we remove this feature and explicitly
transfer the FPU state via the UTCB.

858505918a nova: support EC time in trace subject info 
The vanilla NOVA kernel solely supports tracking and exporting of execution
times per SC kernel object, but not per thread (EC object). The commit extends
to track execution times per EC in the NOVA kernel, exporting it to Genode's
'core' roottask and populating Genode's Trace::Subject_info structure.
