PR target/38736
* c-common.c (handle_aligned_attribute): Use
ATTRIBUTE_ALIGNED_VALUE instead of BIGGEST_ALIGNMENT for
default alignment value.
* c-cppbuiltin.c (c_cpp_builtins): Define __BIGGEST_ALIGNMENT__.
* defaults.h (ATTRIBUTE_ALIGNED_VALUE): New.
* config/i386/i386.h (ATTRIBUTE_ALIGNED_VALUE): Likewise.
* doc/extend.texi: Update __attribute__ ((aligned)). Document
__BIGGEST_ALIGNMENT__.
