[PATCH] pr 60211 - error out if ivdep pragma is outside a function

[tbsaunde+gcc]

From: Trevor Saunders <tbsaunde+...@tbsaunde.org>

Hi,

not doing $subject caused ICES when we tried to parse statements outside of
functions.  Just copy the similar code for other pragmas that effect
statements.


bootstrapped + regtested x86_64-linux-gnu, ok?
