27b2f9e7c2 Implement resolution of variables to the value of the variable once it gets a value

bbfad09fa9 The RTLD_GLOBAL flag allows symbols to be globally accessible, which makes 
resolution of symbols in the .so possible (currently assists debugging with
bugpoint).

3ed1a8d26b Add support for Set statements without {}'s. Now we can just say 
set Foo = bar in
  def blah: blahclass {}

991f66b7e2 Include llvm/Support/Mangler.h first. Don't include <iostream>, <set>, 
<string>, or llvm/Value.h.  Move up the inclusion of llvm/Support/Mangler.h.

d9979a5529 Cleanups: 
Mangler.cpp: Constify parameter to makeNameProper, and use const_iterator.
 Make Count an unsigned int, and use utostr().
 Don't name parameters things that start with underscore.
Mangler.h: All of the above, and also: Add Emacs mode-line.  Include <set>.

6ad460b336 Simplify code by using ConstantInt::getRawValue instead of checking to see 
whether the constant is signed or unsigned, then casting

8a57ef8390 Added a DEBUG() guard to a debug information printout.

d0f2196d2e Fixed a bug: outputting name of variable instead of its value. 
Also, placed DEBUG() guards around debug information so that the generated file
is much smaller and hence should be faster to preprocess/compile.

414c95141f This optimization greatly enhances efficiency of creating new instructions by 
masking and shifting operands directly into their place in the instruction,
instead of the old-fashioned way of ORing in each bit separately.

73f1bbeecd Stop using the `Offset' variable, as we are cycling through the bits of a field 
initializer and the loop index variable already carries the offset information
that we need.

4681b27a92 Isolate machine-dependent use of <alloca.h> in "Support/Alloca.h", 
so that we can easily change its use to be conditional on the result of
an autoconf test later.

7ac52038b0 Updated to the new Makefile.common. 
Modified the test rule so that it can be added to the regular test rule
(I believe the term is double dependency?).

de307f15d4 * Stop ignoring cc registers, since we actually use them in branches. 
* Added comment as to why we are still ignoring predict and annul bits.

I figure that misha has done a lot of things on my todo list, the least I
can do is reciprocate a bit.  :)

170b9ffe76 * Now outputting a static function getBinaryCodeForInstr() (JIT-accessible) 
* For debugging purposes:
  + output the predefined bit pattern of the instruction
* Fixed inefficiency: only load an operand from MachineInstr once
* Bug fix: did not advance bit index when seeing named bit-fields "annul", "cc"
  and "predict"
* Added a catch-all for non-supported instructions at the end of switch stmt.
