Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

of lea.  It is better for code size (and presumably efficiency) to use:

  movl $foo, %eax

rather than:

  leal foo, eax

Both give a nice zero extending "move immediate" instruction, the former is just
smaller.  Note that global addresses should be handled different by the x86
backend, but I chose to follow the style already in place and add more fixme's.

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.
