Spin-off of bug 11718, comment 1. The original test case and reduced version
are fixed, so this seems to be another issue.

cat > test.d << code
mixin template M()
{
    struct S {}
}
mixin M!();
mixin M!();
alias S T; /* should generate an error about conflicting symbols */
code

2.059's behaviour is the correct one, as far as I can tell.

fix Issue 11767 - doubly mixed-in struct "failed semantic analysis"

Inherently this is a mangling issue, which had been hidden since
2a3db5d7afd0c26e8a0ec58ff6fb6a8cd9647de6, and then detected by [the assertion
for AST sanity](20fe5e8600498fed322a7d5d8305acb2de852cde).

Each mixed-in symbols are in independent scope, and their mangled names should
also be different.
To fix the issue, assign scope-local unique name for each unnamed
`TemplateMixin`s, as same as lambdas.
