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

+ want to both have kernel-specific group segment size and multiple
+ kernels calling the same functions that use function scope group memory
+ variables. Now group segment is handled by separate book keeping of
+ module scope and function (kernel) offsets. Each function has a "frame"
+ in the group segment offset to which is given as an argument.
