[PATCH] testsuite, algol68: Add support for dg-timeout-factor and use it for whole-1.a68.

[Iain Sandoe]

Tested on x86_64, i686-darwin and on x86_64-linux where without it whole-1
fails.  OK for trunk?
thanks

Whole-1.a68 fails on some test platforms (in some cases reliably, in some cases
sporadically, depending on load).  It is close to the 20s limit set by the 
algol68
driver.

This adds the capability to use dg-timeout-factor and uses it to double the 
allowed
time for this test.

gcc/testsuite/ChangeLog:

        * algol68/execute/whole-1.a68: Allow 2x timeout.
        * lib/algol68.exp: Add support for dg-timeout-factor.
