Log Message:
------------
Removed all uses of the (deleted) -C1X:+UseXIR option.
Fixed bug in ControlFlowOptimizer that allowed a block implmenting an 
infinite (but reachable) loop to be incorrectly deleted.

Removed code that did eager block ellision/merging when inlining a single 
basic-block callee during bytecode parsing. This legacy optimization was 
required in C1 before it implemented any global optimizations.

Removed redundant javadoc from MaxRiMethod and MaxRiField (it is inherited 
from the interface method javadoc).
