  68         Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
  69         is given, these optimizations are disabled.  With this flag, gccbrig
  70         can generate GENERIC that assumes we are targeting a phsa-runtime
  71         based implementation, which allows us to expose the work-item context
  72         accesses to retrieve WI IDs etc.  which helps optimizers.
  73         First optimization that takes advantage of this is to get rid of
  74         the setworkitemid calls whenever we have non-inlined calls that
  75         use IDs internally.  Other optimizations added in this commit:
  76         - expand absoluteid to similar level of simplicity as workitemid.
  77         At the moment absoluteid is the best indexing ID to end up with
  78         WG vectorization.
  79         - propagate ID variables closer to their uses. This is mainly
  80         to avoid known useless casts, which confuse at least scalar
  81         evolution analysis.
  82         - use signed long long for storing IDs. Unsigned integers have
  83         defined wraparound semantics, which confuse at least scalar
  84         evolution analysis, leading to unvectorizable WI loops.
  85         - also refactor some BRIG function generation helpers to brig_function.
  86         - no point in having the wi-loop as a for-loop. It's really
  87         a do...while and SCEV can analyze it just fine still.
  88         - add consts to ptrs etc. in BRIG builtin defs.
  89         Improves optimization opportunities.
  90         - add qualifiers to generated function parameters.
  91         Const and restrict on the hidden local/private pointers,
  92         the arg buffer and the context pointer help some optimizations.

 263         * brig-lang.c: Improved support for function and module scope
 264         group segment variables.  PRM specs defines function and module
 265         scope group segment variables as an experimental feature. However,
 266         PRM test suite uses and hcc relies on them. In addition, hcc
 267         assumes certain group variable layout in its dynamic group segment
 268         allocation code.  We cannot have global group memory offsets if we
 269         want to both have kernel-specific group segment size and multiple
 270         kernels calling the same functions that use function scope group memory
 271         variables.  Now group segment is handled by separate book keeping of
 272         module scope and function (kernel) offsets. Each function has a "frame"
 273         in the group segment offset to which is given as an argument.
