  Log Message:
  -----------
  [HLSL] Support -E option for HLSL.

-E option will set entry function for hlsl.
The format is -E entry_name.

To avoid conflict with existing option with name 'E', add an extra prefix '--'.

A new field HLSLEntry is added to TargetOption.
To share code with HLSLShaderAttr, entry function will be add HLSLShaderAttr attribute too.
