Patch to implement XFmode/TFmode constant suffixes on IA64

Patch to implement XFmode/TFmode constant suffixes on IA64

[Steve Ellcey]

When the patch to allow the use of 'q' and 'w' suffixes went in for
i386, the tests that were added were also enabled for IA64 but the code
to allow these suffixes was not put in.  Here is a patch to implement
the suffixes for IA64, it is basically the same code that i386 uses.

It fixes:

OK for checkin?

Works for me.  I will check it in.

This patch can be considered as obvious due to the above reason.
