[incomplete patch] Get objdump to report exception tables for ARM/SH4 correctly

[Danny Backx]

[Retry to send this message without the attachment that probably blocked
 the earlier attempt.]

I've attached a patch that'll get objdump to report exception tables
correctly for ARM and SH4 which, according to MSDN, have a different
format for storing the pdata segment.

Here's part of the output, used on a test executable :
dannypc: {642} tail ~/tmp/arm/test/exception/syntax.od
 0000603c       00000000 00000000 00000000 00000000 00000000

The Function Table (interpreted .pdata section contents)
 vma:           Begin    Prolog   Function Flags    Exception EH
                Address  Length   Length   32b exc  Handler   Data
 00014000       00011008 00000002 000fffff  1   1   000110f8  00000000

(handler) 

private flags = 820: [APCS-32] [floats passed in integer registers]
[absolute position] [interworking not supported]

I have three uncertainties with this patch :
1. I've copied code from elsewhere in binutils. Just want to point to
the fact that I did this; I don't think this one is worth exporting as a
public API.
2. Cleanup in my_symbol_for_address. There's none now. Should there be?
3. Which macros should be used for the conditional compilation ? I've
used
#if defined(ARM_WINCE) || defined(SH4)
in my code. This happens to work for me because our build chain defines
ARM_WINCE, but I don't suppose this is right.

Attached are :
- a sample ChangeLog entry
- the patch in its current state
- a gzipped sample file on which this can be used to produce the output
as above. I've renamed it slightly, to avoid virus scanners.

Please advise on how to proceed.
