A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the fifth batch of tests being updated (there are a significant
number of other tests left to be updated).
Note, the behavior of -ast-print is broken. It prints functions with a
prototype (void) as if they have no prototype () in C. Some tests need
to disable strict prototype checking when recompiling the results of an
-ast-print invocation.
See PR51842.
This fixes an assert firing in the static analyzer, triggered by implicit moves
in blocks in C mode:
This also simplifies the AST a little bit when compiling non C++ code,
as the xvalue implicit casts are not inserted.
We keep and test that the nrvo flag is still being set on the VarDecls,
as that is still a bit beneficial while not really making anything
more complicated.
