Pekka Jääskeläinen 080dc24383 [BRIGFE] phsa-specific optimizations
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.

Pekka Jääskeläinen 1b40975c87 [BRIGFE] fix an alloca stack underflow
We didn't preserve additional space for the alloca frame pointers that
are needed to be saved in the alloca space.

Fixes libgomp.c++/target-6.C execution test.

Pekka Jääskeläinen d4b7f2ee4b [BRIGFE] 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.

Pekka Jääskeläinen c02bffe38a BRIGFE fixes:
* brig-builtins.def: Treat HSAIL barrier builtins as
  setjmp/longjump style functions.

* brigfrontend/brig-to-generic.cc: Ensure per WI copies of
  private variables are aligned too.

* rt/workitems.c: Assume the host runtime allocates the work group
  memory.

Pekka Jääskeläinen c6e334cdb1 Minor BRIG/HSAIL frontend updates and bug fixes:
* brig-builtins.def: Added a builtin for class_f64.
* builtin-types.def: Added a builtin type needed by class_f64.
* brigfrontend/brig-code-entry-handler.cc
 (brig_code_entry_handler::build_address_operand): Fix a bug
 with reg+offset addressing on 32b segments. In large mode,
 the offset is treated as 32bits unless it's global, readonly or
 kernarg address space.
* rt/workitems.c: Removed a leftover comment.
* rt/arithmetic.c (__hsail_class_f32, __hsail_class_f64): Fix the
 check for signaling/non-signalling NaN. Add class_f64 default
 implementation.
