Another sighting of this bug in nightly:

New INSTRUMENT_REGRESSION failures (from 2009.01.27)
*   java/lang/instrument/RedefineClassWithNativeMethod.sh
        This test failed the following assertion on Linux IA32 Client
        VM -Xmixed (machine colfax003):

            Internal Error (src/share/vm/code/relocInfo.hpp:1089)
            Error: assert(target != __null,"must not be null")

        This failure mode is covered by the following bug:

            6777083 4/4 assert(target != __null,"must not be null")

        I will copy this entry to 6777083.

            Error: assert(target != __null,"must not be null")

        on Linux IA32 Client VM -Xmixed (machine colfax003). This
        failure occurred during the MakeJAR.sh portion of test setup.
        However, the VM used for JAR creation was the same VM being
        tested so this is still a valid failure.

        This failure is an occurrence of the following bug:

        I will add this entry to 6777083.

This another instance of the problem where byte_map_base == NULL and the code generators aren't ready to deal with it.  6717457 was the last one we fixed of this.  It seems like a more systematic fix is needed.

I suspect we should just disable the use of external word relocations with byte_map_base and simply treat it as an integer.  This is what the compilers do in generated code so it's not clear why we should jump through hoops in other assembly to allow it for no benefit.

6777083: assert(target != __null,"must not be null")
Reviewed-by: iveresov, kvn

ExternalAddress is often used to generate code for references to the
byte_map_base of the card table.  Depending on the address layout we
get byte_map_base may be a real address looking value or sometimes it
maybe a small number or even zero.  This causes
external_word_relocation to assert because the encoding it uses
assumes that the adress isn't within the first page.  This has been
patched up at each use site in the past but keeps recurring as new
code gets written.  To fix this I've modified ExternalAddress to drop
the reloc in the case where it's not encodable.  It's almost
impossible to force a layout where byte_map_base is a small number but
injecting a small number into it indicates that the assembly code
generation works correcty after the change.
