Several Improvements to the Stmt HTML.

[mcourteaux]

Improvements to the Stmt HTML:

• Better alignment for Let expression chains.
• Clearer predicated stores by putting the predicate first, on a separate line.
• Put gaps between stores if the store value has Let expressions in it.
• Rainbow parentheses toggle in the UI.
• Display alignment of Loads and Stores
• Display streaming keyword in front of Loads and Stores.

The formatting of the predicated store and the Let-chains is now more in line with how the IRPrinter does it.

Before (wall of text):

After (one Let per line, and rainbow parentheses):
