PR c++/54955 - Fail to parse alignas expr at the beginning of a declaration
In this PR, g++ embarrassingly fails to parse the simple alignas
expression below:
alignas(double) int f;
even though the simple-declaration production in Clause 7 suggests
otherwise.
Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.

PR c++/54955
* parser.c (cp_nth_tokens_can_be_std_attribute_p): Recognize the
'Alignas' keyword as the beginning of a c++11 attribute specifier.
Update the comment of the function.
(cp_next_tokens_can_be_gnu_attribute_p): Update the comment of the
function.
