Yaxun (Sam) Liu 053e61d54e Relands "[HIP] Change default --gpu-max-threads-per-block value to 1024" 
This reverts commit e384e94fbe.

Fangrui Song fd739804e0 [test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences 
For a default visibility external linkage definition, dso_local is set for ELF
-fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar
to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences.

To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition,
which sets dso_local for default visibility external linkage definitions.

To make this flip smooth and enable future (dso_local as definition default),
this patch replaces (function) `define ` with `define{{.*}} `,
(variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

Yaxun (Sam) Liu 62dbb7e54c Revert "[HIP] Change default --gpu-max-threads-per-block value to 1024" 
Temporarily revert commit 04abbb3a78
due to regressions in some HIP apps due backend issues revealed by
this change.

Will re-commit it when backend issues are fixed.

Yaxun Liu aa24601f98 [CUDA][HIP] Allow CUDA __global__ functions to have amdgpu kernel attributes 
There are HIP applications e.g. Tensorflow 1.3 using amdgpu kernel attributes, however
currently they are only allowed on OpenCL kernel functions.

This patch will allow amdgpu kernel attributes to be applied to CUDA/HIP __global__
functions.
