0845cbe277 name types inside functions after variable 
Before this commit:

    fn f() []const u8 {
        const S = struct {};
        return @typeName(S);  // "f()", unexpected.
    }

And now:

    fn f() []const u8 {
        const S = struct {};
        return @typeName(S);  // "S", expected.
    }

Fixes #675.

bb39e503c0 fix struct inside function referencing local const 
closes #672

the crash and compile errors are fixed but structs
inside functions still get named after the functions
they're in. this will be fixed later.

0ea50b3157 ir: new pass iteration strategy 
Before:
 * IR basic blocks are in arbitrary order
 * when doing an IR pass, when a block is encountered, code
   must look at all the instructions in the old basic block,
   determine what blocks are referenced, and queue up those
   old basic blocks first.
 * This had a bug (See #667)

Now:
 * IR basic blocks are required to be in an order that guarantees
   they will be referenced by a branch, before any instructions
   within are referenced.
   ir pass1 is updated to meet this constraint.
 * When doing an IR pass, we iterate over old basic blocks
   in the order they appear. Blocks which have not been
   referenced are discarded.
 * After the pass is complete, we must iterate again to look
   for old basic blocks which now point to incomplete new
   basic blocks, due to comptime code generation.
 * This last part can probably be optimized - most of the time
   we don't need to iterate over the basic block again.
