108ecf3975 Add support for the __sync_sub_and_fetch atomics and friends for X86. The code
was already present, but not hooked up to anything.

d3aedf445c Fast-isel is now *minimally* functional. Add a testcase to
demonstrate the extent of its capabilities. Note that it
only attempts to operate on one of the blocks in this
testcase.

712c9f0690 The fast-path still needs to set kill markers and spill/restore points as appropriate.

the SimpleSpiller and this fast-path enabled.

assembler.

242330371b Change WriteTypeSymbolic/WriteAsOperand to return void instead of
an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.
