static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.

* standardize cache value names
* organize configure script per autoconf recommendations (10 sections)
* Eliminate some redundancies and complexities in the script
* Provide better documentation in the script.

LLVM blocks as the keys for the branch rewriter.  This fixes treeadd and
many other programs with the JIT.

* Add relocations for refernces to non-lazy darwin stubs and implement
  them correctly.

With this change, we can correctly references external globals, and now
all but two UnitTests and all but 1 Regression/C tests pass.

More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)

obscure problem where we were doing:

lmw     r3,0(r9)

which is undefined on PPC.  Now we do:

lmw     r3,0(r2)

by force, not relying on the GCC register allocator for luck :)

  optional so that compatibility with GCC is accomplished.
* Implement the -print-file-name option in an attempt to provide the same
  functionality as GCC. Unfortunately, without loading the cpp or c config
  files, this option won't help much.

  sub-tool to start reading its standard input instead of the specified
  input.
* Clean up ouput of path names on error.
* Extend GetPathForLinkageItem to always search the LibraryPaths and thus
  make it suitable for an interface function (required by llvmc.cpp).
* Implement support for language-specific default library paths.

llvm-svn: 18188

Add the GetPathForLinkageItem method to the interface so full paths can
be generated for a given linkage item.
