  Log Message:
  -----------
  [SPIRV][SPIRVPrepareGlobals] Convert llvm.embedded.module from a 0-element array to a 1-element array

When compiling with -fembed-bitcode-marker, Clang inserts a placeholder
for the bitcode. This placeholder is a [0 x i8] array, which we cannot
represent in SPIRV.

For AMD flavoured SPIRV, we extend the llvm.embedded.module global to a
zeroinitialized 1-element array.
