Motivation
Reduce linking time by embedding GPU LLVM IR code for Flang runtime.
Technical Details
Modified Flang runtime (added ifdefs to eliminate host-specific code from GPU compilation).
Added switch
-nogpuflangrtto disable linking GPU Flang RT by defaultTest Plan
Checked smoke-fort-dev tests with new GPU Flang RT and the old flang_rt.hostdevice.
Test Result
I was able to compile and successfully run tests without flang_rt.hostdevice flag.
