Add option to join live intervals. Two intervals are joined if there
...
is a move between two registers, at least one of the registers is
virtual and the two live intervals do not overlap.
This results in about 40% reduction in intervals, 30% decrease in the
register allocators running time and a 20% increase in peephole
optimizations (mainly move eliminations).
The option can be enabled by passing -join-liveintervals where
appropriate.

that register if it is available instead of a random one in the free
pool.

This substantially shrinks the size of each machine instruction, which should
make allocation faster and the cache footprint of the machine code lighter.
