c3981dc548 Align functions to 16-byte boundaries, to eliminate noise in performance measurements. This improves the performance of 'treeadd' by about 20% with the dag 
isel, restoring it to the pattern-isel level (which happens to get the alignment right).

e24ce3bb28 Local labels on darwin apparently start with just 'L', not .L like other 
platforms.  This reduces executable size and makes shark realize the actual
bounds of functions instead of showing each MBB as a function :)

362eff4ccd Nate noticed that 30% of the malloc/frees in llc come from calls to LowercaseString 
in the asmprinter.  This changes the .td files to use lower case register names,
avoiding the need to do this call.  This speeds up the asmprinter from 1.52s
to 1.06s on kc++ in a release build.

93820f4ad7 Consolidate the GPOpt stuff to all use the Subtarget, instead of still 
depending on the command line option.  Now the command line option just
sets the subtarget as appropriate.  G5 opts will now default to on on
G5-enabled nightly testers among other machines.

6405f5e9b3 Enable optimization suggested by Chris Lattner to not emit reloc stubs for 
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.
