hacks to improve parsing of complex hi, lo, zda, etc
expressions.
(md_assemble): Don't demand and eat a trailing ')' after finding
a v850 relocation prefix. Sign extend the constant in a

operand.

finding a v850 relocation prefix.

Fixes PR10503. The compiler was producing the assembler code:
dli $3,0xfffffffffffff
when constructing the softfloat library. Unfortunately it was being
incorrectly assembled.
routines to fetch/store the updated instruction from/to memory.

Don't call ffs on openVMS/Alpha.
#ifndef OBJ_ELF lines. From Eric Valette <valette@crf.canon.fr>.
(tc_gen_reloc): If out of memory call as_fatal rather than
assert. If no howto found, call as_bad_where rather than
as_fatal. Change the error message slightly. Set howto to a
non-NULL value in order to keep going.

pre-cursor to adding Thumb support. Also added cpu_variant flag
