Chris Lattner a51f5eeac1 Rename some methods, use 'begin' instead of 'start', add new LiveInterval
iterator/begin/end members.

Alkis Evlogimenos 9f82237f4e Change the way we choose a free register: instead of picking the first
free allocatable register, we prefer the a free one with the most uses
of inactive intervals.

Reid Spencer 7c16caa336 Changes For Bug 352
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Alkis Evlogimenos fae8f6a4fb Be a bit more efficient when processing the active and inactive
lists. Instead of scanning the vector backwards, scan it forward and
swap each element we want to erase. Then at the end erase all removed
intervals at once. This doesn't save much: 0.08s out of 4s when
compiling 176.gcc.

Alkis Evlogimenos e2d962e0fd Now that LiveIntervals::addIntervalsForSpills is fixed, do not require
LiveVariables.

Alkis Evlogimenos efd40bce75 Back out this change as it broke the build last night. This should be
investicated further as the linearscan variants don't really need
LiveVariables...

Alkis Evlogimenos 11f0fc8eda The linear scan variants do not require the LiveVariables analysis.

Alkis Evlogimenos cf72e7f854 Change std::map<unsigned, LiveInterval*> into a std::map<unsigned,
LiveInterval>. This saves some space and removes the pointer
indirection caused by following the pointer.

Chris Lattner c51866a20e Completely eliminate the intervals_ list. instead, the r2iMap_ maintains
ownership of the intervals.

Alkis Evlogimenos 120187935d Use reverse iterators when updating the vector, since scanning from
the end will reduce erase() runtimes.

Alkis Evlogimenos a3efc03731 Change std::list into a std::vector for IntervalSets. This reduces
compile time for 176.gcc from 5.6 secs to 4.7 secs.
