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.

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.

Get rid of the last non-DebugLoc versions of getNode!
...
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base. There's no
sensible way to associate debug info with these. I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands.
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.
