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.

* 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.
From-SVN: r253160
* 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.

* rt/sat_arithmetic.c (__hsail_sat_add_u32, __hsail_sat_add_u64,
__hsail_sat_add_s32, __hsail_sat_add_s64): Use __builtin_add_overflow.
(__hsail_sat_sub_u8, __hsail_sat_sub_u16): Remove pointless for overflow
over maximum.
(__hsail_sat_sub_u32, __hsail_sat_sub_u64, __hsail_sat_sub_s32,
__hsail_sat_sub_s64): Use __builtin_sub_overflow.
(__hsail_sat_mul_u32, __hsail_sat_mul_u64, __hsail_sat_mul_s32,
__hsail_sat_mul_s64): Use __builtin_mul_overflow.

__builtin_sub_overflow_p.
(__hsail_carry_u32, __hsail_carry_u64): Use __builtin_add_overflow_p.
* rt/misc.c (__hsail_groupbaseptr, __hsail_kernargbaseptr_u64):
Cast pointers to uintptr_t first before casting to some other integral
type.
* rt/segment.c (__hsail_segmentp_private, __hsail_segmentp_group): Likewise.
* rt/queue.c (__hsail_ldqueuereadindex, __hsail_ldqueuewriteindex,
__hsail_addqueuewriteindex, __hsail_casqueuewriteindex,
__hsail_stqueuereadindex, __hsail_stqueuewriteindex): Cast integral value
to uintptr_t first before casting to pointer.
* rt/workitems.c (__hsail_alloca_pop_frame): Cast memcpy first argument to
void * to avoid warning.
