Test testbounds.d and testbounds2.d with permute switches

Change from () to (-inline -release -g -O)

From 2.063, conversion slice to static array will be supported ([issue 3652](http://d.puremagic.com/issues/show_bug.cgi?id=3652) and others).
To make the code tough, I had tried to change test option as above, but [bug 9781](http://d.puremagic.com/issues/show_bug.cgi?id=9781) had blocked it. Now the bug was fixed by @dawgfoto in #1874, so I'd like to apply this.
