VK_GOTOFF reloc. This matches as' behavior, but it is not clear why the linker
might need this, so I added a FIXME.

I could test this by duplicating test/MC/ELF/got.s, but it doesn't look
worthwhile.

Parsing a register name/number for .cfi directives can't assume that a
register name starts with a '%' token. Be more flexible and check for a
register number instead. Still unlikely to be perfect, but it allows us
to parse both plain identifiers as register names and integers as register
numbers, which is what we're wanting to support at this point.

Fix up all callers of the affected functions. Make them pass said suffix to
the function.

- Flip order of bitfields. This gets our output matching GAS.
- Handle case where the end of the prolog wasn't specified.
- If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes.

Add a test for the latter two.

Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with
chained unwind areas exposed by the test that were related to this.

The ChainedParent field had the wrong address, because when the chained unwind
info was added, the addresses shifted around. Now we store the pointers to the
structures, which are now allocated from the MC heap.

I had to add a special SwitchSectionNoChange method to MCStreamer just for
.seh_handlerdata. If this isn't OK, please let me know, and I'll find some
other way to fix .seh_handlerdata streaming.

I haven't implemented any of the ones that take registers yet. The problem is
that for x86-64 the streamer methods expect a native x86 register number (note:
%r8-%r15 want 8-15 instead of 0-7; same for %xmm8-%xmm15). I haven't figured
out exactly how I want to do that yet.

There's really nothing to implement. All this really does is swap to a
