FastISel: constrain the RegClass of operands when emitting instructions.

ARM64 suffered multiple -verify-machineinstr failures (principally over the
xsp/xzr issue) because FastISel was completely ignoring which subset of the
general-purpose registers each instruction required.

More fixes are coming in ARM64 specific FastISel, but this should cover the
generic problems.

AArch64/ARM64: copy patterns for fixed-point conversions

Code is mostly copied directly across, with a slight extension of the
ISelDAGToDAG function so that it can cope with the floating-point constants
being behind a litpool.

AArch64/ARM64: add half as a storage type on ARM64.

This brings it into line with the AArch64 behaviour and should open the way for
certain OpenCL features.

AArch64/ARM64: add support for large code-model jump tables.

I've left the MachO CodeGen as it is, there's a reasonable chance it should use
the GOT like ConstPools, but I'm not certain.

AArch64/ARM64: only mangle MOVZ/MOVN during encoding when needed

Sometimes we need emit the bits that would actually be a MOVN when producing a
relocated MOVZ instruction (don't ask). But not always, a check which ARM64 got
wrong until now.

verify-di: split out VerifierSupport

Split out assertion and output helpers from Verifier in preparation for
writing the DebugInfoVerifier.

verify-di: Implement DebugInfoVerifier

Implement DebugInfoVerifier, which steals verification relying on
DebugInfoFinder from Verifier.

  - Adds LegacyDebugInfoVerifierPassPass, a ModulePass which wraps
    DebugInfoVerifier.  Uses -verify-di command-line flag.

  - Change verifyModule() to invoke DebugInfoVerifier as well as
    Verifier.

  - Add a call to createDebugInfoVerifierPass() wherever there was a
    call to createVerifierPass().

This implementation as a module pass should sidestep efficiency issues,
allowing us to turn debug info verification back on.
