Add lock prefix support to x86.  Also add the instructions necessary for the atomic ops.  They are still marked pseudo, since I cannot figure out what format to use, but they are the correct opcode.

This pass transforms 

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal void @foo(%struct._Point* sret  %agg.result)

into

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal %struct._Point @foo()

This pass updates foo() clients appropriately to use
getresult instruction to extract return values.

This pass is not yet ready for prime time.

a union containing a vector and an array whose elements were smaller than
the vector elements.  this means we need to compile the load of the 
array elements into an extract element plus a truncate.

No need for coalescer to update kills. Only copies are coalesced and those instructions will be deleted. Doh.

for non-Darwin.)
