Tobias Koppers 53a1d6c7b5 replace harmonyModule flag with exportsType 3-state 
exportsType falsy: It's non-harmony module
exportsType "namespace": It's a harmony module, the exports is the namespace object
exportsType "default": It's a harmony module, the exports is the default exports, named exports are properties of the default export

Joe Lencioni 37d70bd0c6 Avoid calling hash.update multiple times in ConcatenatedModules 
@sokra did some profiling and it seems that calling crypto.update
multiple times is slower than calling it once with a large string.

> As explanation I would guess update calls into node.js C++ + OpenSSL
> while concatenating strings is very optimized in JIT.

To take better advantage of this information, I have rewritten this
performance-sensitive code to build up a concatenated string and then
hash it at the end.

Since we are thinking about performance here, I opted for a regular for
loop instead of using the forEach iterator. I also did some basic
benchmarking of string concatenation strategies and discovered that
separating out the addition of the extra space into its own
concatenation line instead of tacking it on to the end of a single
concatenation might just barely have the edge in terms of performance. I
think it is also very readable this way, so it seems like a good
tradeoff to make: a little lost conciseness for speed.

Joe Lencioni 8fdf411b84 Simplify identifier creation in ConcatenatedModules 
This was implemented in #5997 to fix some memory issues, but I think we
can make this a little more efficient. By using a single forEach instead
of a map, filter, and join, we avoid unnecessary array creations and
iterations.
