Fix reverse scalar storage order issues in IPA-SRA
The IPA-SRA pass introduced in GCC 10 does not always play nice with the
reverse scalar storage order that can be used in structures/records/unions.
Reading the code, the pass apparently correctly detects it but fails to
propagate the information to the rewriting phase in some cases and, in
particular, does not stream it for LTO.

(dump_isra_access): Tweak dump line.
(isra_write_node_summary): Write the reverse flag.
(isra_read_node_info): Read it.
(pull_accesses_from_callee): Test its consistency and copy it.
gcc/testsuite/
