Add GetAddrOfConstantCString method
- Returns addr of constant for argument + '\0'.
- I couldn't think of a better name.
- Move appropriate users of GetAddrOfConstantString to this.
Rename getStringForStringLiteral to GetStringForStringLiteral.
Add GetAddrOfConstantStringFromLiteral
- This combines GetAddrOfConstantString and
GetStringForStringLiteral. This method can be, but is not yet, more
efficient.
Change GetAddrOfConstantString to not add terminating '\0'
