18cb21f2cb Try to make the meaning of 'nocapture' a bit clearer. I 
commented out the line about simplifylibcalls because I
think this doesn't work in the release (it was fixed in
svn after the release branched).

2b1114593e Declare Sentinel fragments as mutable to get rid 
of some pointless casting. This fragment logically
does not belong to ilist anyway, but to "ghostly"
NodeType.

3f2bbd6301 Move code from Main.cpp to the include dir. 
User drivers based on llvmc must all share the initialization code.
Putting main() into libCompilerDriver is not a very good idea IMO (and ld gave
me some strange EH-related error anyway).

3cde18e191 Reorganize llvmc code. 
Move the code from 'llvmc/driver' into a new CompilerDriver library, and change
the build system accordingly. Makes it easier for projects using LLVM to build
their own llvmc-based drivers.

Tested with objdir != srcdir.

6b41d33726 Fix a problem with DAGCombine on 64b targets where folding 
extracts + build_vector into a shuffle would fail, because the
type of the new build_vector would not be legal.  Try harder to
create a legal build_vector type.  Note: this will be totally 
irrelevant once vector_shuffle no longer takes a build_vector for
shuffle mask.

3f56efbf04 Another sentinel optimization. This one should always 
be a win, since almost every interesting function has at least one Argument.

dc34b050a2 Reuse a technique (pioneered for BasicBlocks) of superposing ilist with 
its sentinel. This is quite a win when a function really has a basic block.                  
When the function is just a declaration (and stays so) the old way did not
allocate a sentinel. So this change is most beneficial when the ratio of
function definition to declaration is high. I.e. linkers etc. Incidentally  
these are the most resource demanding applications, so I expect that the
reduced malloc traffic, locality and space savings outweigh the cost of
addition of two pointers to Function.
