Change [1] introduced a regression that results in comparison
in arm_jtag_set_instr() to be always true if the length of the
IR register is not 8 bit. The value on the left side
of the != operator contains only tap->ir_length number of
bits while value on the right is full 8-bit instruction code.
This forces OpenOCD to update the JTAG IR register on each
transaction even if the instruction in the JTAG IR register
is correct. This causes noticeable performance degradation,
especially with slow JTAG adapters.

ARM IHI 0031A does not support SWJ-DP, so no switch between JTAG
and SWD is considered.
ARM IHI 0031B is not publicly available and it's reported as
"Confidential Beta" in the history list in following doc versions.
From ARM IHI 0031C the direct switch between JTAG and SWD is
already deprecated in favor of passing through dormant mode. With
no access to IHI 0031B we haven't info if any device strictly
requires the direct switch.
OpenOCD implements only the deprecated direct switch, so changing
it could cause regression on devices that do not implement dormant
mode.
Plus, not all the adapters support dormant mode.
Nevertheless there are already target devices that only allow
entering in SWD by passing through dormant.
Let the code try both method, alternating one tentative with the
deprecated legacy direct switch, then another tentative passing
through dormant, and repeat till timeout.
This would work on any device that don't support dormant, on new
devices that require switch through dormant and will work with
adapters that don't support dormant.
