This is done to avoid odd test failures, like the one fixed in r171243.

Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.2012-12-20T16:04:27ZJames Molloyjames.molloy@arm.com2012-12-20T16:04:27Zurn:sha1:67ae13575900e8efd056672987249fd0adbf5e73
Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

Teach loop rotate to hoist trivially invariant instructions2010-09-06T01:10:22ZChris Lattnersabre@nondot.org2010-09-06T01:10:22Zurn:sha1:50fb46983ccae116bdbda64471f4861108766135
in the duplicated block instead of duplicating them.
Duplicating them into the end of the loop and the preheader
means that we got a phi node in the header of the loop,
which prevented LICM from hoisting them. GVN would
usually come around later and merge the duplicated
instructions so we'd get reasonable output... except that
anything dependent on the shoulda-been-hoisted value can't
be hoisted. In PR5319 (which this fixes), a memory value
didn't get promoted.
