Improved error recovery for _Pragma
Summary:
Currently, if the argument to _Pragma is not a parenthesised string
literal, the bad token will be consumed, as well as the ')', if present.
If additional bad tokens are passed to the _Pragma, this results in
extra error messages which may distract from the true problem.
The proposed patch causes all tokens to be consumed until the closing
')' or a new line, whichever is reached first.
