"optimization" about 473.astar (multiversioning + fully-unroll).
Performance impact:

This revision is to strip "try" region if the calls in it won't throw exception.
Enabling flag : -WOPT:nothrow_opt={true|false}
Performance impact: dealII gain 1%-2.8%, not sure if it is noise, likely not.
Implementation details:
-----------------------
A call will not throw exception if it falls in one of the following criterias:
1) it is declared so, e.g. "void* malloc(size_t) nothrow()".
2) leave func
3) all callees won't throw exception.
4) TODO: all potential exceptions are caughted by the function, and
won't pass to caller
Following steps are involved in propagating "no-throw" info:
a) In FE, mark a PU "no-throw" if the function's decl tree say so.
it seems g++ FE is quite smart, not only can it take care criteira 1)
and 2), it is able to handle 3) to some extend.
b) In IPA phase, merge no-throw flags.
c) TODO: in IPA phase, prapogate "no-throw" bottom up along call-graph.
c) In preopt/wopt, analyze if current funtion won't throw exception
based on the criteira above. |

Updates to reassociation pass to use arguments
more effieiciently,handle memory leaks on WHIRL
allocation and then port to use SSA versions instead
of WN_Aux ids enabling the pass to work on SSA form. |
