Sanjiv Gupta 5372d4a568 Code Restructuring. No functionality change.

Sanjiv Gupta 7607eba036 PIC16 emits auto variables as globals. When optimizer removes a function entierly by estimating its side effects on globals, those globals(autos) without a function were not being printed by the Asm printer.

Sanjiv Gupta 43becc23c2 Emit debug information for globals (which include automatic variables as well because on PIC16 they are emitted as globals by the frontend).

Sanjiv Gupta 4a71ae268b Run through the list of globals once and sectionize all types of globlas includeing declarations. Later emit them from their section lists.

Sanjiv Gupta 83adfb4a9f Iterate over globals once and sectionize them into appropriate sections.
Later in asmprinter, go over thsese sections and print them.
Do not print empty sections.

Sanjiv Gupta 9d175c15e7 Detect calls to compiler intrinsics and emit an extern declarations
only for those. These extern declarations to intrinsics are currently 
being emitted at the bottom of generated .s file, which works fine with
gpasm(not sure about MPSAM though).
PIC16 linker generates errors for few cases (function-args/struct_args_5) if you do not include any
extern declarations (even if no intrinsics are being used), but that
needs to be fixed in the linker itself.

Sanjiv Gupta 960ae0660b Emit banksel and movlp instructions.
Split large global data (both initialized and un-initialized) into multiple sections of <= 80 bytes.
Provide routines to manage PIC16 ABI naming conventions.

Bill Wendling 026e5d7667 Instead of passing in an unsigned value for the optimization level, use an enum,
which better identifies what the optimization is doing. And is more flexible for
future uses.

Bill Wendling 084669a1c9 Second attempt:
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

"Fast" flag. I'm not 100% sure if it's necessary to change it there...

Sanjiv Gupta 0b08df8c09 Map stack based frameindices for spills to zero based indices that can be accessed based on an external symbol defining the location of temporary data for a function. For example: we have spill slots addressed as foo.tmp + 0, foo.tmp + 1 etc.

Sanjiv Gupta 1e8860a8f5 Params are not being generated as static globals now. The caller passes them onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots.

Evan Cheng 5e5a63cf8f CodeGen still defaults to non-verbose asm, but llc now overrides it and default to verbose.

Bill Wendling c5437ea429 Overhaul my earlier submission due to feedback. It's a large patch, but most of
them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

Sanjiv Gupta 964a29f671 Enable emitting of constant values in non-default address space as well. The APIs emitting constants now take an additional parameter signifying the address space in which to emit. The APIs like getData8BitsDirective() etc are made virtual enabling targets to be able to define appropirate directivers for various sizes and address spaces.
