61a0c964e6 sim: syscall: unify memory helpers
Almost every port implements these two callbacks in the same way, so
unify them in the common layer.

5b064994f0 sim: msp430: use new common trace print helpers
Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx".
The output is the same, but the code is nicer to read.

c1e768db52 sim: msp430: use common warnings options
This triggers a bunch of new warnings, so fix some of them.

10d602c7f9 Fix the detection of illegal memory accesses in the MSP430 simulator.
* msp430-sim.c (sim_open): Allocate memory regions matching those
	declared in the libgloss/msp430 linker scripts.
	Allow sim_load_file to fail.
	(get_op): Test the correct address bit when checking for out of
	range addresses.
	Include the address in the error message when an illegal access to
	the hardware multiplier is detected.
	(put_op): Test the correct address bit when checking for out of
	range addresses.

180eb0634c Replace static variables in the MSP430 simulator with fields in the cpu state structure.
* msp430-sim.c: Move static hardware multiply support variables
	from here...
	* msp430-sim.h (msp430_cpu_state): ... into here ...
	* msp430-sim.c (get_op, put_op): ... and update references to use
	the msp430_cpu_state structure.

aef392c4ae Fix a small but in the emulation of the MSP430 hardware multiply.
* msp430-sim.c (get_op): Handle reads of low result register when
	in MAC mode.
	(put_op): Copy MAC result into result words.
	Handle writes to the low result register.

a7da346e5c Support 32->64 sign extension in msp430's sign_ext
* msp43-sim.c (sign_ext): Change to "long long" to support
sign-extending 32-bit values.

8969934d31 Add support for emulating the MSP430 hardware multiply feature.
* msp430-sim.c (sim_open): Do not allocate memory over the
	hardware multiply registers.
	(get_op): Add support for reads from the hardware multiply
	registers.
	(put_op): Add support for writes to the hardware multiply
	registers.
	(msp430_step_once): Add support for the RETI instruction used by
	the CPUX architecture.

7b0278dcad sim: msp430: set initial PC to ELF entry if available
If we want to run a simple ELF, the reset vector isn't set up, so starting
at address 0 doesn't make sense.  Use the ELF's entry point instead.

a3271a3e6c sim: msp430: fix build time warnings
This fix is simple:

msp430-sim.c: In function 'maybe_perform_syscall':
msp430-sim.c:898:10: warning: format '%d' expects argument of type 'int',
                     but argument 5 has type 'long int' [-Wformat]

This one we change to use casts like everyone else does in the code base:

msp430-sim.c: In function 'msp430_step_once':
msp430-sim.c:985:7: warning: passing argument 3 of 'init_disassemble_info'
                    from incompatible pointer type [enabled by default]
include/dis-asm.h:368:13: note: expected 'fprintf_ftype' but argument is
of type 'int (*)(struct FILE * __restrict__,  const char * __restrict__)'
