New APIs:
(*BasicBlock).{Idom,Dominees,Dominates}
(*Function).DomPreorder
Messy but systematic refactoring of domNode:
- renamed "domInfo".
- embedded directly in BasicBlock, not as pointer. Block field removed.
- Level field removed; was unused.
- Working state of LT algorithm now in its own type.
{semi,parent,ancestor} fields moved into it.
- remaining fields made private; accessors added.
- use 32-bit ints for pre/postorder numbers.
- allocate LT working space (5 copies of fn.Blocks) contiguously.
dom.go is simpler but somewhat more verbose.
Also:
- we always build the domtree now---yet memory usage is down 5%.
- number the Recover block too.
- add sanity check for DomPreorder.

README
This subrepository holds the source for various packages and tools that support the Go programming language. Some of the tools, godoc and vet for example, are included in binary Go distributions. Others, including the Go oracle and the test coverage tool, can be fetched with "go get". Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs. To submit changes to this repository, see http://golang.org/doc/contribute.html.
