Clean up vestigial code for constants in PNaCl bitcode files.
* Removes code that is no longer used because global variables are handled
separately.
* Removes CST_CODE_NULL.
* Adds special abbreviations for constant integer 0, replacing
most of what was lost when CST_CODE_NULL is removed.
* Adds abbreviation for floating point constants.
* Removes CST_CODE_AGGREGATE and CST_CODE_DATA, except for reading
old PNaCl version 1 bitcode files.
* Removes call to ParseConstants() in ParseModule() since the module
block no longer contains a constants block (globals are handled
separately).
* Removes getConstantFwdRef() method, since it is no longer needed.
* Remove ConstantPlaceHolder class, since it is no longer needed.
* Remove ResolvedConstants and ResolveConstantForwardRefs()
from the bitcode reader, since it is no longer needed.
