X64 Crankshaft: Ported lots of boilerplate code.

X64 Crankshaft: Ported lots of boilerplate code. 
Small tweaks to make X64 compliant. 
A few UNIMPLEMENTED left, but most empty functions call Abort to bail out.

LGTM.

LGTM
This is a lot of code to review without knowing which part in particular was
changed compared to ia32. I would like to take a closer look in kompare
tomorrow.

I am also uncertain about the setup of the different methods in lithium-x64, but
I guess we need to change this when we actually do the codegen anyway so this is
fine by me for the moment.

Lets file a bug for this if it needs to be fixed- Thomas probably will not fix
this.

LGTM, we should probably update it to be exactly consistent with ia32 specific
files before committing since they changed a bit since this cl was uploaded 
(and then keep it this way when changing the ia32 specific files)
