New Revision: 93153
URL: http://llvm.org/viewvc/llvm-project?rev=93153&view=rev
Log:
Roll out ASTContext::getTypeSizeInChars(), replacing instances of
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate.
Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType,
fromQuantity(), and getQuantity() for clarity.
