Fix the execution of the MSP430 simulator testsuite. 

ld	* emulparams/msp430elf.sh (RAM_START): Move to 0x500 - above the
	MSP430 hardware multiply address range.
	* scripttempl/elf32msp430.sc (__romdatastart): Define.
	(__romdatacopysize): Define.
	* scripttempl/elf32msp430_3.sc: Likewise.

tests	* testutils.inc (__pass): Use the LMA addresses of the _passmsg
	symbol.
	(__fail): Likewise.

.global __pass
.type __pass, function
__pass:
write 1, _passmsg, 5
# Note - we cannot just invoke:
#
# write 1, _passmsg, 5
#
# here because _passmsg contains the run-time (VMA) address of
# the pass string (probably 0x500) not the load-time (LMA)
# address (probably 0x804c). Normally using the VMA address
# would be the correct thing to do - *if* there was some start
# up code which copied data from LMA to VMA. But we have no
# start up code, so the data still resides at the LMA
# address. Hence we use __romdatastart instead.
#
# Note - we are cheating because the address that we pass to
# "write" should actually be:
#
# __romdatastart + (_passmsg - __datastart)
#
# but the assembler cannot cope with this expression. So we
# cheat and use the fact that we know that _passmsg is the
# first string in the .data section and so (_passmsg -
# __datastart) evaluates to zero.
