The only supported calling convention for X86-64 uses
...
SSE, so we can't return floating point values if this
is disabled. Detect this error for clang.
With SSE1 only, f64 is a problem; it can be done, but
neither llvm-gcc nor clang has ever generated correct
code for it. Since nobody noticed this I think it's
OK to treat it as an error for now.
This also handles SSE-sized vectors of floating point.

switch a private implementation of GetFunctionSizeInBytes.

This is probably not the best way to implement "Force LR to
be spilled if the Thumb function size is > 2048." do this,
it should use the branch shortening infrastructure, but I'm
just preserving functionality here.

instead of migrating it to the MC instruction encoder, just
...
rip out the implementation of X86InstrInfo::GetInstSizeInBytes.
The code being ripped out just implemented a copy and hacked up
version of the (old) instruction encoder, and is buggy and
terrible in other ways. Since "GetInstSizeInBytes" is really
only there to support the JIT's "NeedsExactSize" hook (which
noone is using), just rip out the code. I will rip out the
NeedsExactSize hook next.
This resolves rdar://7617809 - switch X86InstrInfo::GetInstSizeInBytes to use X86MCCodeEmitter
