and don't emit the tokens that the macros are defined to.

1. Sinking would crash when the first instruction of a block was
   sunk due to iterator problems.
2. Instructions could be sunk to their current block, causing an
   infinite loop.

With this we generate

movl    %gs:0, %eax
leal    i@NTPOFF(%eax), %eax

instead of

movl    $i@NTPOFF, %eax
addl    %gs:0, %eax

A CodeTextRegion wraps two kinds of data: FunctionDecl* or SymbolRef. 
The latter comes from the symbolic function pointer that are generated from
function calls or input data.

improvement, source locations read from the PCH file will properly
resolve to the source files that were used to build the PCH file
itself.

Once we have the preprocessor state stored in the PCH file, source
locations that refer to macro instantiations that occur in the PCH
file should have the appropriate instantiation information.

Fix: <rdar://problem/6776949> Branch condition evaluates to an uninitialized value (argc is guaranteed to be >= 1)

The analyzer now adds the precondition that the first argument of 'main' is > 0.
