c++: Don't reject pointer to virtual method during constant evaluation [PR117615]

We currently reject the following valid code:

=== cut here ===

The problem is that since r6-4014-gdcdbc004d531b4, &Derived::doit is
represented with an expression with type pointer to method and using an

Martin Jambor [Fri, 15 Nov 2024 13:37:06 +0000 (14:37 +0100)] 
tree-sra: Avoid SRAing arguments to a function returning_twice (PR 117142)

This is a manual bacport of commit
29d8f1f0b7ad3c69b3bdb130325300d5f73aa784 which must be done slightly
elsewhere for gcc 13 and 12 because function
build_access_from_call_arg was added only in gcc 14.

But the gist of the patch is the same.  The commit message of the
original fix says:

PR 117142 shows that the current SRA probably never worked reliably
with arguments passed to a function returning twice, because it then
creates statements before the call which however needs to be at the
beginning of a basic block.

While it should be possible to make at least the case of passing
arguments by value work with SRA (the statements would need to be put
just on the non-abnormal edges leading to the BB), this would mean
large surgery of function sra_modify_expr and I guess the time would
better be spent re-organizing the whole pass.

c++: Defer -fstrong-eval-order processing to template instantiation time [PR117158]

Since r10-3793-g1a37b6d9a7e57c, we ICE upon the following valid code
with -std=c++17 and above

=== cut here ===
struct Base {
  unsigned int *intarray;
};
template <typename T> struct Sub : public Base {
  bool Get(int i) {
    return (Base::intarray[++i] == 0);
  }
};
=== cut here ===

The problem is that from c++17 on, we use -fstrong-eval-order and need
to wrap the array access expression into a SAVE_EXPR. We do so at
template declaration time, and end up calling contains_placeholder_p
with a SCOPE_REF, that it does not handle well.

This patch fixes this by deferring the wrapping into SAVE_EXPR to
instantiation time for templates, when the SCOPE_REF will have been
turned into a COMPONENT_REF.
