85c5465e07 Convert RegClass::IsColorUsedArr from a dynamically allocated array to
a vector.  This makes asserting on array bounds easier.

0243ff9e62 InstrnsBefore and InstrnsAfter are now vectors instead of deques.
May be slightly less efficient but significantly reduces special

dabb41d93d Numerous bug fixes:
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

d0c668c380 Two Cleanups to generated C code:
1. Avoid printing *(&globalvariable), instead print globalvariable alone
   as a special case.
2. Inline subexpressions into expressions as much as legal that preserves
   execution characteristics of expressions.  Now we get nice (but
   over-parenthesized, oh well) things like:

     ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream));

   instead of five seperate instructions (bsBuff & bsStream are globals).

  if (l2_cond240) {
    goto l13_bb10;
  }

  easier to read without it.
