 Add NOINLINE for hs-boot functions

 This fixes Trac #10083.

 The key change is in TcBinds.tcValBinds, where we construct
 the prag_fn.  With this patch we add a NOINLINE pragma for
 any functions that were exported by the hs-boot file for this
 module.

 See Note [Inlining and hs-boot files], and #10083, for details.

 The commit touches several other files becuase I also changed the
 representation of the "pragma function" from a function TcPragFun
 to an environment, TcPragEnv. This makes it easer to extend
 during construction.
