New thread testcase (resubmit)

[Manoj Iyer <manjo@austin.ibm.com>]

[-- Attachment #1: Type: TEXT/PLAIN, Size: 673 bytes --]


I have attached two modified versions of my new thread testcase.

- version 1
incorporates Michael Chastain's suggestions and it includes
the step and backtrace tests from the thread fucntion.

-version 2
incorporates Michael Snyder suggestion to remove the step and backtrace
tests from the testcase.

Please let me know which one you like and any other comments or changes.
ChangeLog is pasted at the begning of the patch.

+# - run gdb till #1 main() breakpoint is reached
+# - continue to breakpoint #2 tf()
+# - single step to first instruction in the thread function tf()
+# - backtrace from thread function tf()
+# - delete all breakpoints 
+# - exit gdb.
