Fixed 6826960: C2 Sparc: assert(bb->_nodes[_bb_end]->is_Proj(),"skipping projections after expected call")

Problem:
Scheduling code expects Halt nodes only after uncommon_trap calls.
The fix for 6823453 generates Halt nodes for unreachable paths
after allocations. Such Halt nodes are placed in separate blocks.

Solution:
Add the check when a Halt node is placed in a separate block.
