cb72d92471 Add pass to promote sret. 
This pass transforms 

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal void @foo(%struct._Point* sret  %agg.result)

into

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal %struct._Point @foo()

This pass updates foo() clients appropriately to use
getresult instruction to extract return values.

This pass is not yet ready for prime time.

75f5d14574 fix a bug Anders ran into where scalarrepl would crash when promoting 
a union containing a vector and an array whose elements were smaller than
the vector elements.  this means we need to compile the load of the 
array elements into an extract element plus a truncate.

35d58dcc00 Use the new convertFromAPInt instead of convertFromZeroExtendedInteger, 
which allows more of the surrounding arithmetic to be done with APInt
instead of uint64_t.

6efc4a5c4d Simplify and clean up "update" target. Also 
add an SVN-UPDATE-OPTIONS variable that controls
the update behaviour. This allows to go to a common
older revision of all svn directories:

  gmake update SVN-UPDATE-OPTIONS=-r47717

would rewind both llvm and clang to a common
revision (if clang is checked out into the llvm
tree).

dd987bc788 Now that targets are serialized, introduce 
two new convenience targets:

- update: svn update toplevel and try hard
          to locate updatable subdirectories
					using cunning tricks
- happiness: update then build and test

so what one wants to do now is:
  nice gmake --jobs happiness

Have fun!

596fb7b39f Treat all targets serially at the toplevel. This allows 
to specify
  nice gmake --jobs all check
and go to lunch, while a multiprocessor machine
will build everything using spare resources
and check the result thereafter.
Since concurrency of make is not restricted
in subdirectories, this should be a nearly
optimal way to do it.

Also teach the user about a configure switch.
