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).

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).
llvm-svn: 65825
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.

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.

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.
