EVALUATION 6875026: CTW failure jdk6_18/hotspot/src/share/vm/c1/c1_LinearScan.cpp:5486 Reviewed-by: kvn, iveresov Constructing the CodeEmitInfo for an instruciton may result in evaluation of instructions which are only used in the ValueStack. This should always been done before any argument setup with fixed registers. arraycopy uses all the registers and this can cause us to fail our allocation. The fix is to make the code look like the sparc code and create the CodeEmitInfo early. Tested with test from report.
