Clarify when we can avoid creating names for temp symbols.

Some temporary symbols are created by MC itself. These symbols are never used
for lookup and are never included in the object symbol table, so we can
avoid creating a name for them.

Other temporaries are created by CodeGen or by the user by explicitly asking
for a name starting with .L (or L on MachO).

These temporaries behave like regular symbols, we just try to avoid including
them in the object symbol table, but sometimes they end up there:

const char *foo() {
  return "abc" + 3;
}

will have a relocation pointing to a .L symbol.

It just so happens that almost all MC created temporary has the AlwaysAddSuffix
option and CodeGen/user created ones don't.

One interesting future optimization would be to use unnamed symbols for
all temporaries, but that would require use an st_name of 0 or
having the object writer create the names if a symbol does end up in the
symbol table.

temporaries.

9 years ago[RewriteStatepointsForGC] Strip deref info after rewriting.

[RewriteStatepointsForGC] Strip deref info after rewriting.

Summary:
Once a gc.statepoint has been rewritten to relocate live references, the
SSA values represent physical pointers instead of logical references.
Logical dereferencability does not imply physical dereferencability and
after RewriteStatepointsForGC has run any attributes that imply
dereferencability of the logical references need to be stripped.

This current approach is conservative, and can be made more precise
later if needed.  For starters, we need to strip dereferencable
attributes only from pointers that live in the GC address space.

[SelectionDAG] Fix PR23603.

Summary:
LLVM's MI level notion of invariant_load is different from LLVM's IR
level notion of invariant_load with respect to dereferenceability.  The
IR notion of invariant_load only guarantees that all *non-faulting*
invariant loads result in the same value.  The MI notion of invariant
load guarantees that the load can be legally moved to any location
within its containing function.  The MI notion of invariant_load is
stronger than the IR notion of invariant_load -- an MI invariant_load is
an IR invariant_load + a guarantee that the location being loaded from
is dereferenceable throughout the function's lifetime.
