Comments: Set "optimization is ON" and supply other optional parameters. This helps codegenerator preserve info in case the symbol is deleted.

Comments: Added -fno-honor-nans (-fhonor-nans is the default) and -fno-honor-infinites (-fhonor-inifinites is the default). These allow optimizations for fp math to assume the arguments and results are not NaNs / +-Infs respectively.

-ffinite-math-only implies -fno-honor-nans and -fno-honor-infinites.

Comments: Handle code gen for the unreachable instruction if it's the only instruction in
the function. We'll just turn it into a "trap" instruction instead.

The problem with not handling this is that it might generate a prologue without
the equivalent epilogue to go with it:

$ cat t.ll
define void @foo() {
entry:
  unreachable
}
$ llc -o - t.ll -relocation-model=pic -disable-fp-elim -unwind-tables
        .section        __TEXT,__text,regular,pure_instructions
        .globl  _foo
        .align  4, 0x90
_foo:                                   ## @foo
Leh_func_begin0:
## BB#0:                                ## %entry
        pushq   %rbp
Ltmp0:
        movq    %rsp, %rbp
Ltmp1:
Leh_func_end0:
...

The unwind tables then have bad data in them causing all sorts of problems.

Fixes <rdar://problem/8096481>.

Comments: Fix the order that SCEVExpander considers add operands in so that
it doesn't miss an opportunity to form a GEP, regardless of the
relative loop depths of the operands. This fixes rdar://8197217.

Comments: When deferring the emission of declarations with initializers in C++, remember
the order they appeared in the translation unit.  If they get emitted, put them
in their proper order.  Fixes rdar://problem/7458115
