 commit f16ddcee0c64a92ab911a7841a8cf64e3ac671fd
 Author: Edward Z. Yang 
 Date:   Mon May 4 16:10:05 2015 -0700

     Support stage 1 Template Haskell (non-quasi) quotes, fixes #10382.

     Summary:
     This commit adds stage 1 support for Template Haskell
     quoting, e.g. [| ... expr ... |], which is useful
     for authors of quasiquoter libraries that do not actually
     need splices.  The TemplateHaskell extension now does not
     unconditionally fail; it only fails if the renamer encounters
     a splice that it can't run.

     In order to make sure the referenced data structures
     are consistent, template-haskell is now a boot library.
     There are some minor BC changes to template-haskell to make it boot
     on GHC 7.8.

     Note for reviewer: big diff changes are simply code
     being moved out of an ifdef; there was no other substantive
     change to that code.
