799c1ede71 Delete the linear scan register allocator. 
RegAllocGreedy has been the default for six months now.

Deleting RegAllocLinearScan makes it possible to also delete
VirtRegRewriter and clean up the spiller code.

d752e0f7e6 Added invariant field to the DAG.getLoad method and changed all calls. 
When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

37efc9fe42 Begin collecting some of the statistics for block placement discussed on 
the mailing list. Suggestions for other statistics to collect would be
awesome. =]

Currently these are implemented as a separate pass guarded by a separate
flag. I'm not thrilled by that, but I wanted to be able to collect the
statistics for the old code placement as well as the new in order to
have a point of comparison. I'm planning on folding them into the single
pass if / when there is only one pass of interest.

613b757689 First part of support for generating dwarf for assembly source files with the 
-g flag.  In this part we generate the .file for the source being assembled and
the .loc's for the assembled instructions.

The next part will be to generate the dwarf Compile Unit DIE and a dwarf
subprogram DIE for each non-temporary label.

Once the next part is done test cases will be added.  rdar://9275556
