On 64bit we may have a personality function which requires 64 bits to
...
be encoded.

Implement support for JIT exceptions on X86_64. Relative offsets are
...
encoded on 32 bytes, and the personality function is not encoded as
relative.

Update the JIT exception writer to better mimic the codegen exception writer.
...
Also skip indirect encoding for platforms that ask for one: we direclty
write an address, not a pointer to the address.

Move SLEB/ULEB size calculation routines from AsmPrinter to TargetAsmInfo. This makes JIT asmprinter-free.

Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating
...
the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.
Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.
This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.

Clean up the use of static and anonymous namespaces. This turned up

several things that were neither in an anonymous namespace nor static
but not intended to be global.
