[5/5,v2] Add tests for 64bit values in trace-condition.exp

This patch adds tests for emit operations with 64 bit values. It takes
special care to avoid mistakes that one could make on a 32bit architecture
using 64bit values.

gdb/testsuite/ChangeLog:

	* gdb.trace/trace-condition.exp: Add 64bit tests.

Same comment on splitting the counter-cases to their own section.
It's very hard to match the counter-case with the corresponding "case" 
test this way IMO.  Could you resort please?  Maybe even add an empty
line between each pair of case/counter-case, for added legibility.

Thanks,
