glcpp: Don't enter lexer's NEWLINE_CATCHUP start state for single-line comments

In commit 6005e9cb28 a new start state of NEWLINE_CATCHUP was added to the
lexer. This start state is used whenever the lexer is emitting a NEWLINE token
to emit additional NEWLINE tokens for any newline characters that were skipped
by an immediately preceding multi-line comment.

However, that commit erroneously entered the NEWLINE_CATCHUP state for
single-line comments. This is not desired since in the case of a single-line
comment, the lexer is not emitting any NEWLINE token. The result is that the
lexer will remain in the NEWLINE_CATCHUP state and proceed to fail to emit a
NEWLINE token for the subsequent newline character, (since the case to match \n expects only the INITIAL start state).

The fix is quite simple, remove the "BEGIN NEWLINE_CATCHUP" code from the
single-line comment case, (preserving it only in exactly the cases where the
lexer is actually emitting a NEWLINE token).

Many thanks to Petri Latvala for reporting this bug and for providing the
minimal test case to exercise it. The bug showed up only with a multi-line
comment which was followed immediately by a single-line comment (without any
intervening newline), such as:

	/*
        */ // Kablam!

Since 6005e9cb28, and before this commit, that very innocent-looking
combination of comments would yield a parse failure in the compiler.

glcpp: Rename the variable used to enable debugging.

The -p option we now use when calling bison means that this variable will be
named glcpp_parser_debug not yydebug. This was not caught when the -p option
was added because this variable isn't used in the code as committed. (I prefer
the declaration to remain since it allows a developer to easily find this
variable name to enable debugging.)

The code re-enabling denorms for small float formats did not recognize
this format due to format handling hacks (mainly, the lp_type doesn't have
