Chris Lattner 956820d989 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.

Chris Lattner 983a415b6a 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.

don't support things like memcpy directly.  This allows a handful of the
Shootout programs to work, yay!

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to

Nate Begeman 43123c9f7a Remove the ISel->AsmPrinter link via the TargetMachine that was put in 
place to help bring up the PowerPC back end on Darwin.  This code is no
longer serves any purpose now that the AsmPrinter does the right thing
all the time printing GlobalValues.  --Cruft.

Nate Begeman 3f76eb69f6 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.
