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.

* cache more values
* 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.

* 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.

terminate options or paths, so that SPACE tokens legally separate options
on a command line, and so that the lang.libs paths are parsed properly.
