tree-sra: Do not create stores into const aggregates (PR111873)
This patch fixes (hopefully the) one remaining place where gimple SRA
was still creating a load into const aggregates. It occurs when there
is a replacement for a load but that replacement is not type
compatible - typically because it is a single field structure.
I have used testcases from duplicates because the original test-case
no longer reproduces for me.

PR tree-optimization/111873
* tree-sra.cc (sra_modify_expr): When processing a load which has
a type-incompatible replacement, do not store the contents of the
replacement into the original aggregate when that aggregate is
const.
