d67a1e3fa8 Make sure that if anyone passes a name by accident for the isSigned 
parameter of CreateIntCast then they get an error from the compiler
(or from the linker with a non-gcc compiler).  Another possibility
is to flip the order of the DestTy and isSigned parameters, since you
should then get a compiler warning if you try to use a char* for a
Type*.

6469fa6824 Support spill comments. 
Have the asm printer emit a comment if an instruction is a spill or
reload and have the spiller mark copies it introdues so the asm printer
can also annotate those.

a name.

21ca44ba49 - Fix a small bug while handling target constant pools (one param was missing). 
- Add a smarter constant pool loading, instead of:

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)
lwc1 $f0, %lo($CPI1_0)($2)

Make sure when ProcessImplicitDefs removes a copy which kills its source reg that it
removes the copy from said reg's Kills list.

(because the invalidation logic is missing) but LVI isn't enabled
by default anyway.

94b8fd17c7 mark getIntrinsicID() 'readonly'. This allows various classof methods 
(like DbgDeclareInst's) to shrink substantially.  It sucks that we have
to pull Compiler.h into such a public header, but at least Compiler.h
doesn't pull anything else in.
