New virtual registers created for spill intervals should inherit allocation hints from the original register.
...
This helps us avoid silly copies when rematting values that are copied to a physical register:
leaq _.str44(%rip), %rcx
movq %rcx, %rsi
call _strcmp
becomes:
leaq _.str44(%rip), %rsi
call _strcmp
The coalescer will not touch the movq because that would tie down the physical register.

indirect branches are limited by other factors so code size does not change
much due to tail duplicating indirect branches aggressively.

Graphviz can layout the graphs better if a node does not contain source

that means are not labeled with the empty string "".
This patch also simplifies graphs without any edgeSourceLabels e.g. the
dominance trees.
