f7da2c7b0c Take advantage of the recent improvements to the liveintervals set (tracking 
instructions which define each value#) to simplify and improve the coallescer.
In particular, this patch:

1. Implements iterative coallescing.
2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a
   better solution.
3. Implements PR865, "coallescing" away the second copy in code like:

   A = B
   ...
   B = A

This also includes changes to symbolically print registers in intervals
when possible.

6f4c60770c Make the ProgramName variable a std::string so we can eliminate the path 
portion fo the program name via sys::Path().getLast(). This makes error
messages more readable since this is invariably used only in error
messages.  Instead of:
  /path/to/llvm/bin/directory/toolname: error message
we will now get:
  toolname: error message
Also, since we always have a program name (even if its defaulted), don't
check to see if it is set or not when generating error messages. This
eliminates a bunch of constant strings, saving a little under 1K of data.

ab96bb1df3 Rearrange the build order to better accommodate parallel build by reducing 
memory pressure. This order spaces out large executables with small ones in
between so that in a -j2 or -j3 build, it only attempts to build only one
large executable at time. If you're doing -j4, you probably have enuogh
memory anyway.
