Use __device__ for all variables and functions to be used in kernel path
Abolish __device and adopt [[hc]] in HIP implementation, so __device__ can be
used on all HIP applications, no matter they are variables or functions.

XXX FIXME get around LDS spills caused in Promote-free HCC
hipDynamicShared2 uses all 64KB of LDS for computation. But in Promote-free HCC
there are cases where LDS spills would occur, which would make the test case to
hang.
In this workaround commit we reduce the size of dynamic LDS used to get around
this known issue, and will revert this commit when LDS spills are resolved in
HCC.

Changes to cope with Promote-free HCC
- abolish usage of address_space GNU attribute
- use __device in file-scope global variables which would be accessed by GPU kernels
- temporarily disable some math functions which take pointer arguments

1. All fp32, fp64 math device/host functions should be in math_functions.h/.cpp
2. All fp32, fp64 fast math intrinsics for device/host functions should be in device_functions.h/.cpp
3. All the device code implementations should be in device_util.h/.cpp
4. Hence, made changes appropriately by moving code and creating new header files
5. Added math_functions.cpp/.h
6. Changed #ifndef signature to make sure no conflicts between headers with same names in hip/hip_runtime.h and hip/hcc_detail/hip_runtime.h
7. Changed tests to fit the code changes, making them to include appropriate headers
8. Added math_functions.cpp to CMakeLists.txt
9. Some of the tests are still broken, mostly host math functions will fix them in next commit
10. TODO: FIX compilation issues for host math functions
Change-Id: I7a17637d7e294a7d224ffba932c1a08668febd26
1. Added all type conversion intrinsics
2. NO TESTS have been added. (Will add in next commit)
3. Sanatized code in hip_runtime.h
4. Added passed() to hipTestHalf to make it pass on HIT
Change-Id: I0987963c802fc7ff4d7e07d7b88d86da35da53c9
1. Added fast math intrinsics for single precision data types
2. Added test to check the intrinsics
3. Added HIP_PRECISE_MATH macro to enable precise math on fast math
Change-Id: Iadacbb6182c31252c5e3252854372d1b80dfd27b
1. Added fast math apis for sin, cos, tan, sincos
2. Added test for trig math functions
3. Added logarithm fast math
4. Changed how hipGetDevice, hipDeviceGetCacheConfig emit errors
Change-Id: Ie6ab594ddd5853cbe85e39a2f6d3479a807fa323
- Complete translation tables for cudaError <-> hipError_t.
- Remove some odd errors that were not correctly translated or not used.
- Add HIPCHECK_API to test infrastructure. Used for negative testing
an API ; if a mismatch occurs it shows the expected return error
code. Can also print a warning rather than error.
- Enable hipMemoryAllocate on NV system, and review error coded.
- Add hipErrorName to nvcc.

Conflicts:
tests/src/CMakeLists.txt
Bug fixes and improved docs for hipFree and hipHostFree.
- Passing NULL pointer initialized runtime and return hipSuccess
(not an error like before).
- add negative test for this. (hipMemoryAllocate, improved)
- Match NVCC errors for invalid pointers, add to test.
- Update hipFree and hipHostFree docs.
- hipGetDevicePointer always set *devicePointer=NULL, even for
invalid flags.
- Gate shared memory usage on specific HCC work-week.
