performed in the release branch.  This should free up mainline sooner to

used them for a release; Tanya is investigating their integration, and they
can be re-added if she uses them.

be filling that section out later (but before the 1.7 release).

Add insertelement and shufflevector constantexpr support

Fix recursion:
1. Make setting OPTIONAL_DIRS use immediate assignment
2. Include Makefile.config before ifeq tests and then Makefile.rules later
   instead of Makefile.common up front. This ensures that the variable
   values are set before the ifeq statements in Makefile.rules are
   evaluated.
With this, recursion into projects/examples is corrected.

INSERT_VECTOR_ELT lowering bug:
  store vector to $esp
  store element to $esp + sizeof(VT) * index
  load  vector from $esp
The bug is VT is the type of the vector element, not the type of the vector!
