OpenCL printf handling did not process vector of half precision floats properly
(mainly because compiler packs 2 halfs into a dword and runtime failed to extract the
individual parts).
This patch fixes the issue.

Relates to https://reviews.llvm.org/D150427,
Each printf call populates buffer with following data
1. Control DWord - contains info regarding stream, format string constness and size of data frame
(see http://gerrit-git.amd.com/c/lightning/ec/device-libs/+/857722 for more info)
2. Hash of the format string (if constant) else the format string itself
3. Printf arguments (each aligned to 8 byte boundary)

When HIP_ENABLE_DEFERRED_LOADING=0, many global variables will be
referenced but they are not initialized in that early time. The patch
will use constexpr to initialze global constant varables in compile
time.
