727e11ac33 Rewrite to use the reachability cloner interface. Also, make this much more 
efficient in the case where a function calls into the same graph multiple times
(ie, it either contains multiple calls to the same function, or multiple calls
to functions in the same SCC graph)

2a8df1739b Fix failing test cases with joined live intervals. It turns out that 
when joining we need to check if we overlap with the second interval
or any of its aliases.

out that the problem was actually the writer writing out a 'null' value
because it didn't normalize it.  This fixes:

b4745bda05 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.

2ad4ba012c Move bytecode_libdir def'n to Makefile.config.in from Makefile.rules, so it

a72f3a387a Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.

07d45564d0 Start implementing DSGraph::clonePartiallyInto and implement mergeInGraph 
in terms of it.

Though clonePartiallyInto is not cloning partial graphs yet, this change
dramatically speeds up inlining of graphs with many scalars.  For example,
this change speeds up the BU pass on 253.perlbmk from 69s to 36s, because
it avoids iteration over the scalar map, which can get pretty large.

it does not exist by calling mkinstalldirs.

38664cbb8b To materialize a module, you need to know what functions NEED to be read and 
which ones don't, which is state that the parent class doesn't know without
knowing the implementation. Let the children classes implement
materializeModule().
