RFR: 8265262: CITime - 'other' incorrectly calculated

[Nils Eliasson]

This CR fixes a few issues with the CITIme output for C2:

1) The other category for _t_optimize is not removing time spent in _t_vector

2) Some of the _t_incrInline sub counters is called from different contexts - calculating 'other' from total time spent in _t_incrInline expects that the counter usage is strictly hierarchical.

3) I've placed the non-hierarchical counters in braces.

4) Code Installation is a part of Code Emission (_t_output). Indentation fixed.

5) Moved "renumber live" after "Vector" so that they appear in order.

6) Added sub counters "shorten branches" and "fill buffer" to "Code Emission" phase, and added an other category. Before more than 50% of time in Code Emission was unaccounted for, now it's less than 25%.

Please review,
Best regards,
Nils Eliasson
