x86: Use separate variable for TLSDESC XSAVE/XSAVEC state size (bug 32810) Previously, the initialization code reused the xsave_state_full_size member of struct cpu_features for the TLSDESC state size. However, the tunable processing code assumes that this member has the original XSAVE (non-compact) state size, so that it can use its value if XSAVEC is disabled via tunable. This change uses a separate variable and not a struct member because the value is only needed in ld.so and the static libc, but not in libc.so. As a result, struct cpu_features layout does not change, helping a future backport of this change. Fixes commit 9b7091415af47082664717210ac49d51551456ab ("x86-64: Update _dl_tlsdesc_dynamic to preserve AMX registers"). Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
