Basically, using:
  lea symbol(%rip), %rax

is not valid in -static mode, because the current RIP may not be
within 32-bits of "symbol" when an app is built partially pic and
partially static.  The fix for this is to compile it to:

  lea symbol, %rax

It would be better to codegen this as:

  movq $symbol, %rax

but that will come next.


The hard part of fixing this bug was fixing abi-isel, which was actively
testing for the wrong behavior.  Also, the RUN lines are completely impossible
to understand what they are testing.  To help with this, convert the -static 
x86-64 codegen tests to use filecheck.  This is much more stable and makes it
more clear what the codegen is expected to be.

Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

MachineOperand is a reference to a stub, not a reference to the
global variable itself.  Look no context needed!

started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

registers based on dynamic conditions. For example, X86 EBP/RBP, when used as
frame register has to be spilled in the first fixed object. It should inform
PEI this so it doesn't get allocated another stack object. Also, it should not
be spilled as other callee-saved registers but rather its spilling and restoring
are being handled by emitPrologue and emitEpilogue. Avoid spilling it twice.
