	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.

	Change internal representation of HSA registers. Instead
	representing HSA's untyped registers as unsigned int the gccbrig
	analyzes brig code and builds the register variables as a type
	used in tree expressions at most. This gives better chance to
	optimize CONVERT_VIEW_EXPRs away.

	register type usage. Handle any-typed register variables.

2017-10-09  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>

	* brigfrontend/brig-to-generic.cc: Support BRIG_KIND_NONE
	directives.  These directives are legal everywhere.  They
	can be used to patch away BRIG entries at the binary level.
	Also add extra error detection for zeroed regions: make sure
	the byteCount field is never zero.
	* brig/brigfrontend/phsa.h: Added a new error prefix for
	errors which are due to corrupted BRIG modules.

2017-10-09  Henry Linjamäki  <henry.linjamaki@parmance.com>

	because vector expansion can move the object to another location.

	* brigfrontend/brig-branch-inst-handler.cc: Fix crash with

	with kernels that have both unexpanded ID functions and
	calls to subfunctions.

2017-09-28  Henry Linjamäki  <henry.linjamaki@parmance.com>

	* brig-lang.c: Added function attributes and their handlers.
	Make BRIGFE 3-level optimize by default.

2017-09-27  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>

	* brig-lang.c: Improved support for function and module scope
	group segment variables.  PRM specs defines function and module
	scope group segment variables as an experimental feature. However,
	PRM test suite uses and hcc relies on them. In addition, hcc
	assumes certain group variable layout in its dynamic group segment
	allocation code.  We cannot have global group memory offsets if we
	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.
