Delete now-unnecessary const_casts.

llvm-svn: 101637

Use const qualifiers with TargetLowering. This eliminates several
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static mem

Use const qualifiers with TargetLowering. This eliminates several
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

Revert 101465, it broke internal OpenGL testing.

Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

Use twines to simplify calls to report_fatal_error. For code size and readability.

convert a report_fatal_error that I was able to trigger into a nice error

Three changes:
1. Introduce some enums and accessors in the InlineAsm class
that eliminate a ton of magic numbers when handling inline
asm SDNode.
2. Add a new MDNodeSDNode selection dag node type that holds
a MDNode (shocking!)
3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc
metadata, propagating it to the instruction emitter, which
drops it.

No functionality change.
