This patch deprecates hasValue and getValue for consistency with
std::optional and llvm::Optional. Note that I've migrated all known
uses of them to has_value and value, respectively.

An optional attribute dictionary before a region in an assembly format

This patch adds support for string literals as `custom` directive
arguments. This can be useful for re-using custom parsers and printers
when arguments have a known value. For example:
```
ParseResult parseTypedAttr(AsmParser &parser, Attribute &attr, Type type) {
return parser.parseAttribute(attr, type);
}
void printTypedAttr(AsmPrinter &printer, Attribute attr, Type type) {
return parser.printAttributeWithoutType(attr);
}
```
And in TableGen:
```
def FooOp : ... {
let arguments = (ins AnyAttr:$a);
let assemblyFormat = [{ custom<TypedAttr>($a, "$_builder.getI1Type()")
attr-dict }];
}
def BarOp : ... {
let arguments = (ins AnyAttr:$a);
let assemblyFormat = [{ custom<TypedAttr>($a, "$_builder.getIndexType()")
attr-dict }];
}
```
Instead of writing two separate sets of custom parsers and printers.

`AllOfType` is a type constraint that satisfies all given type

Introduce two different failure propagation mode in the Transform
dialect's Sequence operation. These modes specify whether silenceable
errors produced by nested ops are immediately propagated, thus stopping
the sequence, or suppressed. The latter is useful in end-to-end
transform application scenarios where the user cannot correct the
transformation, but it is robust enough to silenceable failures. It
can be combined with the "alternatives" operation. There is
intentionally no default value to avoid favoring one mode over the
other.
Downstreams can update their tests using:
S='s/sequence \(%.*\) {/sequence \1 failures(propagate) {/'
T='s/sequence {/sequence failures(propagate) {/'

c7ec6e19d5 made LLVM adhere to the x86
psABI and pass bf16 in SSE registers instead of GPRs. This breaks the
custom versions of runtime functions we have for bf16 conversion. A
great fix for this would be to use __bf16 types instead which carry the
right ABI, but that type isn't widely available.
Instead just pretend it's a 32 bit float on the ABI boundary and
carefully cast it to the right type.
