<li>LLVM generates substantially better code for indirect gotos due to a new
tail duplication pass, which can be a substantial performance win for
interpreter loops that use them.</li>

+<li>Exception handling and debug frame information is now emitted with CFI
+ directives. This lets the assembler produce more compact info as it knows
+ the final offsets, yielding <a href="http://blog.mozilla.com/respindola/2011/05/12/cfi-directives/">much smaller executables</a> for some C++ applications.

+ the integrated assembler is not used.
<li>The code generator now supports vector "select" operations on vector
