C'mon everybody, let's modify X86JITInfo.cpp. This time, we add <iostream>
...
so that the shiny new use of std::cerr is defined.

* Change assert() to std::cerr printout, as it will not appear in opt builds
* Add comments to clarify what #ifdef/#else/#endif match what condition(s)

Use target-specific nodes for calls. This allows the fastcc code to not have
...
to do ugly hackery to avoid emitting code like this:
call foo
mov vreg, EAX
adjcallstackup ...
If foo is a fastcc call and if vreg gets spilled, we might end up with this:
call foo
mov [ESP+offset], EAX ;; Offset doesn't consider the 12!
sub ESP, 12
Which is bad. The previous hacky code to deal with this was A) gross B) not
good enough. In particular, it could miss cases and emit the bad code above.
Now we always emit this:
call foo
adjcallstackup ...
mov vreg, EAX
directly.
This makes fastcc with callees poping the stack work much better. Next
stop (finally!) really is tail calls.

Do not CopyFromReg physregs for live-in values. Instead, create a vreg for

each live in, and copy the regs from the vregs. As the very first thing we
do in the function, insert copies from the pregs to the vregs. This fixes
problems where the token chain of CopyFromReg was not enough to allow reordering
of the copyfromreg nodes and other unchained nodes (e.g. div, which clobbers
eax on intel).
