I stumbled over this change while trying to integrate LLVM head into our
downstream project. Is there any way to enforce that this still prints textual
IR in the old format, i.e., without "splat"? I found the following flags, but
they do not seem to provide the expected behavior.
```
--use-constant-int-for-fixed-length-splat
--use-constant-fp-for-fixed-length-splat
--use-constant-int-for-scalable-splat
--use-constant-fp-for-scalable-splat
```
What I would require is some way of forcing `opt` to roundtrip on the following
IR file **without** transforming this to splat syntax:
```
define <2 x double> @test(<2 x double> %in) {
%res = fmul <2 x double> %in, <double 3.000000e+00, double 3.000000e+00>
ret <2 x double> %res
}
```
Ofc., we can find other kinds of workarounds, but I wanted to first to confirm
that this is indeed expected behavior or not.
