for bitfield extract, although it is turned off until fully debugged.

* Stop the confusion of using rv and Addr for global addresses: just use rv

* Convert register numbers from their opcode value to the real value, e.g.
  PPC::R1 => 1 and PPC::F1 => 1
* Add correct handling of loading of global values which are PC-relative --
  implement ha16() and lo16()

be listed second as that is how the instructions are usually created (and is the
correct asm syntax) so that it's assembled correctly from its constituents

The decimal value given in the manual (8 or 9) really needs to be multiplied by
a factor of 32 because of the group of 5 zero bits after the register code.

emit unnecessary clear operations for code such as:
int foo(int x) { return 1 << x; }

Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.

This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.

  - Support added for functions, basic blocks, constant pool, constants,
    registers, and some basic support for globals, all untested
* Turn assert()s into abort()s so that unimplemented functions fail in release

loops.  This optimization is not turned on by default yet, but may be run
with the opt tool's -loop-reduce flag.  There are many FIXMEs listed in the
code that will make it far more applicable to a wide range of code, but you
have to start somewhere :)

This limited version currently triggers on the following tests in the
MultiSource directory:
pcompress2: 7 times
cfrac: 5 times
anagram: 2 times
ks: 6 times
yacr2: 2 times
