GCC can't reasonably be told that the lock ptr isn't null. Adding a private bool
allows the branch to be eliminated, along with the bool.

Track pointer info for sub 2MB fragment allocations in allocation_map_.
Add fragment support to IPC.
Change-Id: I00cfc2e2fa289aac90a4718c392f9bb056a61a87
Added an API for creating signals with attributes.
Added two APIs for IPC operations on signals.
Initial use of exceptions for error handling.
Add ref counting to signals.
Removed spin loops from signal destructors.
Signals are no longer to be destroyed with delete, use DeleteSignal instead.
Added delete safety to doorbells.
Added secondary hsa_signal_t -> Signal* translation path for IPC enabled signals.

1. Correct amd::AqlQueue::ExecutePM4 to support interception.
2. Minor fixes to AqlPacket and SoftCP.
3. Minimal change to disable interception of runtime internal queues.

When a fatal memory fault occurs the scheduler context-saves all queues
in the process and notifies the runtime through the memory event. The
saved state contains all GPR/LDS data at the moment of the fault.
Retrieve this state and present it to the user if HSA_DEBUG_FAULT is set
to "analyze" and the wavefront caused the fault. If amdgcn-capable objdump
is in the PATH invoke this to disassemble code around the PC.
Queue lifetime is now managed by the runtime to allow querying the
context save state for all active queues.

The trap protocol changed between gfx8 and gfx9. The return address
is in trap temporaries [0,1] on gfx9 rather than [4,5] on gfx8.
Unfortunately SP3 changes the meaning of the ttmp register aliases
in gfx9, further confusing the issue.
Clean up later when LLVM assembly build is introduced to the runtime.

Informs, in debug mode only, that a signal wait violated the HSA
spec with regard to the consuming agents list. This list is used
for optimized signal type selection.

Should point directly to amd_queue_t.write_dispatch_id. Only noticeable
with HWS enabled which is not yet stable.

- Build system fixes
- No user-mode high-precision timer by default, use clock_gettime
- Use C11 aligned_alloc pending C++17 std::aligned_alloc

Gfx9 requires monotonic write pointer and doorbell.
Cound fields are 1-based compared with 0-based pre-Gfx9.
- Restructure implementation to use monotonic ring indices
- Remove redundant submission size checks (handled by AcquireWriteAddress)
- Unify copy/fill per-command limit (documentation is unclear)
Change-Id: I57c1675221d2e63aa319fee700d9951671e1bd65
Note: Implementation same as 1.0 APIs for now.
The followup change will have the complete implementation.
