Add this to ease debugging why the standard scripts aren't found on the
default script search path in some build/install enviroments. Especially on
Windows it's not straight forward where openocd actually looks for the

These changes seem reasonably to me, but without documentation

Hi all,
This series builds upon the last to cleanup the JTAG layer command
handler registration. First, each module gets converted to use
register_commands() with a command registration array. The final patch
converts the jtag_interface structure to contain the registration list
(and its size),

It's harder to screw up with the new way of doing things, as the
registration parameters are more explicit. It also eliminates a lot of
redundant calls to register_command{,s}
I'm trying to get rid of most I know how the register cache
is laid out knowledge, and eventually to make the ARM11 code
use the standard register framework. These are stepping stones
along that path.
- ARM11: remove useless #defines
- simplify CPSR access
- define set_cpsr() and a mapping
Minor cleanup of ARM11 register handling: remove disabled
register hooks. This should all be handled by shared code,
and this stuff is just clutter.

Define arm_reg_current() ... returning handle to a given register,
and encapsulating the current mode's register shadowing. It's got
one current use, for reporting the current register set to GDB.
This will let later patches clean up much ARMV4_5_CORE_REG_MODE()
nastiness, saving a bit of code.
Have arm_set_cpsr() handle the two core state flags, updating
the CPU state. This eliminates code in various debug_entry()
paths, and marginally improves handling of the J bit.
Catch and comment a few holes in the handling of the J bit on
ARM926ejs cores ... it's unlikely our users will care
Start using the arm_reg_current() call. This shrinks and speeds
the affected code. It can also prevent some coredumps coming from
invalid CPSR values ... the ARMV4_5_CORE_REG_MODE() macro returns
bogus registers if e.g. Secure Monitor mode isn't supported by
the current CPU.

Stash a pointer to the CPSR in the struct arm, to help get rid
