utils.h provides have_hwcap() and have_hwcap2() which check for a
feature bit. Those bits are defined in asm/cputable.h, so include it
in utils.h so users of utils.h don't have to do it manually.

TM test tm-unavailable must take into account aborts due to host aborting
a transactin because of a facility unavailable exception, just like it
already does for aborts on reschedules (TM_CAUSE_KVM_RESCHED).

There are cases where the test is not expecting to have the transaction
aborted, but, the test process might have been rescheduled, either in the
OS level or by KVM (if it is running on a KVM guest machine). The process
reschedule will cause a treclaim/recheckpoint which will cause the
transaction to doom, aborting the transaction as soon as the process is
rescheduled back to the CPU. This might cause the test to fail, but this is
not a failure in essence.
If that is the case, TEXASR[FC] is indicated with either
TM_CAUSE_RESCHEDULE or TM_CAUSE_KVM_RESCHEDULE for KVM interruptions.
In this scenario, ignore these two failures and avoid the whole test to
return failure.

Add a self test to check if FP/VEC/VSX registers are sane (restored
correctly) after a FP/VEC/VSX unavailable exception is caught during a
transaction.
This test checks all possibilities in a thread regarding the combination
of MSR.[FP|VEC] states in a thread and for each scenario raises a
FP/VEC/VSX unavailable exception in transactional state, verifying if
vs0 and vs32 registers, which are representatives of FP/VEC/VSX reg
sets, are not corrupted.

There are some functions, especially register related, which can
be shared across multiple selftests/powerpc test directories.
This patch creates a new include directory to store those shared
files, so that the file layout becomes more neat.

Perform an exec() class syscall with a suspended transaction.
This is a test for the bug we fixed in 8e96a87c5431 ("powerpc/tm: Always
reclaim in start_thread() for exec() class syscalls").

Move have_htm_nosc() into a new tm.h, and add a new helper, have_htm()
which we'll use in the next patch.
