Manually resolved some conflicts:
- Use internal/strconv for simd.String, remove internal/ftoa
- prove.go is just copied from the one on the main branch. We
have cherry-picked the changes to prove.go to main branch, so
our copy is identical to an old version of the one on the main
branch. There are CLs landed after our cherry-picks. Just copy
it over to adopt the new code.

For a compiler intrinsic, if it is used in a non-call context, e.g.
as a function pointer, currently it requires fallback
implementation (e.g. assembly code for atomic operations),
otherwise it will result in a build failure. The fallback
implementation needs to be maintained and tested, albeit rarely
used in practice.
Also, for SIMD, we're currently adding a large number of compiler
intrinsics without providing fallback implementations (we might in
the future). As methods, it is not unlikely that they are used in
a non-call context, e.g. referenced from the type descriptor.
This CL lets the compiler generate the function body for
bodyless intrinsics. The compiler already recognizes a call to
the function as an intrinsic and can directly generate code for it.
So we just fill in the body with a call to the same function.

When creating a new *ir.Name or *ir.LinksymOffsetExpr to represent
a composite literal stored in the read-only data section, we should
use the original type of the expression that was found via
ir.ReassignOracle.StaticValue. (This is needed because the StaticValue
method can traverse through OCONVNOP operations to find its final
result.)
Otherwise, the compilation may succeed, but the linker might erroneously
conclude that a type is not used and prune an itab when it should not,
leading to a call at execution-time to runtime.unreachableMethod, which
throws "fatal error: unreachable method called. linker bug?".
The tests exercise both the case of a zero value struct literal that
can be represented by the read-only runtime.zeroVal, which was the case
of the simplified example from #73888, and also modifies that example to
test the non zero value struct literal case.
This CL makes two similar changes for those two cases. We can get either
of the tests we are adding to fail independently if we only make
a single corresponding change.

Add a new helper type 'ReassignOracle', useful for doing "batch mode"
reassignment analysis, e.g. deciding whether a given ir.Name or (chain
of connected names) has a single definition and is never reassigned.
The intended usage model is for clients to create/initialize a
ReassignOracle for a given function, then make a series of queries
using it (with the understanding that changing/mutating the func body
IR can invalidate the info cached in the oracle). This oracle is
intended to provide the same sort of analysis that ir.StaticValue and
ir.Reassigned carry out, but at a much reduced cost in compile
time.
Notes:
- the new helper isn't actually used for anything useful in this
patch; it will be hooked into the inline heuristics code as part of
a subsequent CL.
- this is probably not an ideal long-term solution; it would be better
to switch to a scheme based a flag on ir.Name, as opposed to a
side table.

Today, the PGO IR graph only contains entries for ir.Func loaded into
the package. This can include functions from transitive dependencies,
but only if they happen to be referenced by something in the current
package. If they are not referenced, noder never bothers to load them.
This leads to a deficiency in PGO devirtualization: some callee methods
are available in transitive dependencies but do not devirtualize because
they happen to not get loaded from export data.
Resolve this by adding an explicit lookup from export data of callees
mentioned in the profile.
I have chosen to do this during loading of the profile for simplicity:
the PGO IR graph always contains all of the functions we might need.
That said, it isn't strictly necessary. PGO devirtualization could do
the lookup lazily if it decides it actually needs a method. This saves
work at the expense of a bit more complexity, but I've chosen the
simpler approach for now as I measured the cost of this as significantly
less than the rest of PGO loading.
For #61577.

One of the more tedious quirks of the original frontend (i.e.,
typecheck) to preserve was that it preserved the original
representation of constants into the backend. To fit into the unified
IR model, I ended up implementing a fairly heavyweight workaround:
simply record the original constant's string expression in the export
data, so that diagnostics could still report it back, and match the
old test expectations.
But now that there's just a single frontend to support, it's easy
enough to just update the test expectations and drop this support for
"raw" constant expressions.

I took the logic from markAddrOf, and failed to notice that
ComputeAddrtaken also set Addrtaken on the canonical ONAME.
The result is that if the only address-of expressions were within a

In turn, this could cause the consistency check in ir.Reassigned to

than miscompilation.)
