x86/hypercall: enable the test on non-KVM environment

KVM knows to emulate both vmcall and vmmcall regardless of the
actual architecture. Native hardware does not behave this way. Based on
the availability of test-device, figure out that the test is run on
non-KVM environment, and if so, run vmcall/vmmcall based on the actual
architecture.

x86: always set up SMP

Currently setup_vm cannot assume that it can invoke IPIs, and therefore
only initializes CR0/CR3/CR4 on the CPU it runs on. In order to keep the
initialization code clean, let's just call smp_init (and therefore
setup_idt) unconditionally.

Switch the order of the parameters in report() and report_xfail()

Switch the order of the parameters in report() and report_xfail()

Commit c09c54c66b1df ("lib: use an argument which doesn't require
default argument promotion") fixed a warning that occurs with Clang,
but introduced a regression: If the "pass" parameter is a value
which has only set the condition bits in the upper 32 bits of a
64 bit value, the condition is now false since the value is truncated
to "unsigned int" so that the upper bits are simply discarded.

We fixed it by reverting the commit, but that of course also means
trouble with Clang again. We can not use "bool" if it is the last
parameter before the variable argument list. The proper fix is to
swap the parameters around and make the format string the last
parameter.

This patch (except the changes in lib/libcflat.h and lib/report.c
and some rebase conflicts along the way) has basically been created
with following coccinelle script (with some additional manual tweaking
of long and disabled lines afterwards):

expression fmt;
expression pass;
expression list args;

report(
-fmt, pass
+pass, fmt
