6579789: Internal error "c1_LinearScan.cpp:1429 Error: assert(false,"")" in debuggee with fastdebug VM
Reviewed-by:

When using the x86 FPU, spilling at an exception entry point may
mutate the intervals so that _sorted_intervals is no longer sorted.
The fix is detect this case and resort as needed.  Additionally I
added some more assertion checks and fixed a printing problem that
would assert on partially allocated intervals.  Tested with new test
case and CTW.
