Subject: [PATCH v2 0/7] Overhauling amx_test

AMX architecture involves several entities such as xstate, XCR0,
IA32_XFD. This series add several missing checks on top of the existing
amx_test.

v1 -> v2:
 - Add a working xstate data structure suggested by seanjc.
 - Split the checking of CR0.TS from the checking of XFD.
 - Fix all the issues pointed by in review.

v1:
https://lore.kernel.org/all/20230110185823.1856951-1-mizhang@google.com/
