These two macros print either a 16 digit hex number or an 8 digit
hex number. Unfortunately they depend on both target and host, which
means that the output for 32-bit targets may be either 8 or 16 hex
digits.
Replace them in most cases with code that prints a bfd_vma using
PRIx64. In some cases, deliberately lose the leading zeros.
This change some output, notably in base/offset fields of m68k
disassembly which I think looks better that way, and in error
messages. I've kept leading zeros in symbol dumps (objdump -t)
and in PE header dumps.

/* While the ia64-opc-* set of opcode tables are easy to maintain,
|
||
they waste a tremendous amount of space. ia64-gen rearranges the
|
||
instructions into a directed acyclic graph (DAG) of instruction opcodes and
|
||
their possible completers, as well as compacting the set of strings used.
|
||
|
||
The disassembler table consists of a state machine that does
|
||
branching based on the bits of the opcode being disassembled. The
|
||
state encodings have been chosen to minimize the amount of space
|
||
required.
|
||
|
||
The resource table is constructed based on some text dependency tables,
|
||
which are also easier to maintain than the final representation. */
