Emit RETL instruction to return instead of funny JMPL.
Fix indentation.

llvm-svn: 12186

Add RET, RETL.  Rename SAVE, RESTORE & JMPL for consistency.

This reduces CBU time from 145s -> 122s (debug build), reduces # allocated nodes
from 129420 to 116477.

The problem was that we were merging a field of a node with a value that was
deleted.  Thanks to bugpoint for reducing povray to a nice small 3 function
example.  :)

Make sure to scope the NodeMap passed into cloneInto so that it doesn't point
to nodes that are deleted.  Add some FIXME's for future performance enhancements.

do it on povray.  The problem is that we were not copying globals from callees to
callers unless the existed in both graphs.  We should have copied them in the case
where the global pointed to a node that was copied as well.

it is always completely initialized and copied.
Also, fix up many comments and asserts.

nodes that were globally live, thus breaking programs.

been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed!  This could improve the
performance of the CBE generated code substantially!
