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
