[Frontend] Recognize environment variable SOURCE_DATE_EPOCH
See https://reproducible-builds.org/docs/source-date-epoch/ . The environment
variable ``SOURCE_DATE_EPOCH`` been recognized by many compilers.
In GCC, if `SOURCE_DATE_EPOCH` is set, it specifies a UNIX timestamp to be used
in replacement of the current date and time in the `__DATE__` and `__TIME__`
macros. Note: GCC as of today does not update `__TIMESTAMP__` (the modification
time of the current source file) but
https://wiki.debian.org/ReproducibleBuilds/TimestampsFromCPPMacros expresses the
intention to update it.
This patches parses SOURCE_DATE_EPOCH and changes all the three macros.

gmtime returns null when the timestamp is larger than

Introduce a ConditionallySpeculatable op interface
This patch takes the first step towards a more principled modeling of undefined behavior in MLIR as discussed in the following discourse threads:
1. https://discourse.llvm.org/t/semantics-modeling-undefined-behavior-and-side-effects/4812
2. https://discourse.llvm.org/t/rfc-mark-tensor-dim-and-memref-dim-as-side-effecting/65729
This patch in particular does the following:
1. Introduces a ConditionallySpeculatable OpInterface that dynamically determines whether an Operation can be speculated.
2. Re-defines `NoSideEffect` to allow undefined behavior, making it necessary but not sufficient for speculation. Also renames it to `NoMemoryEffect`.
3. Makes LICM respect the above semantics.
4. Changes all ops tagged with `NoSideEffect` today to additionally implement ConditionallySpeculatable and mark themselves as always speculatable. This combined trait is named `Pure`. This makes this change NFC.
For out of tree dialects:
1. Replace `NoSideEffect` with `Pure` if the operation does not have any memory effects, undefined behavior or infinite loops.
2. Replace `NoSideEffect` with `NoSideEffect` otherwise.
The next steps in this process are (I'm proposing to do these in upcoming patches):
1. Update operations like `tensor.dim`, `memref.dim`, `scf.for`, `affine.for` to implement a correct hook for `ConditionallySpeculatable`. I'm also happy to update ops in other dialects if the respective dialect owners would like to and can give me some pointers.
2. Update other passes that speculate operations to consult `ConditionallySpeculatable` in addition to `NoMemoryEffect`. I could not find any other than LICM on a quick skim, but I could have missed some.
3. Add some documentation / FAQs detailing the differences between side effects, undefined behavior, speculatabilty.

[Attributes] Make intrinsic attribute generation more flexible (NFC)
Currently attributes for intrinsics are emitted using the
ArrayRef<AttrKind> based constructor for AttributeLists. This works
out fine for simple enum attributes, but doesn't really generalize
to attributes that accept values. We're already doing something
awkward for alignment attributes, and I'd like to have a cleaner
solution to this with
https://discourse.llvm.org/t/rfc-unify-memory-effect-attributes/65579 in mind.
The new generation approach is to instead directly construct
Attributes, giving us access to the full generality of that
interface. To avoid significantly increasing the size of the
generated code, we now also deduplicate the attribute sets. The
code generated per unique AttributeList looks like this:
case 204: {
AS[0] = {1, getIntrinsicArgAttributeSet(C, 5)};
AS[1] = {AttributeList::FunctionIndex, getIntrinsicFnAttributeSet(C, 10)};
NumAttrs = 2;
break;
}
and then the helper functions contain something like
case 5:
return AttributeSet::get(C, {
Attribute::get(C, Attribute::NoCapture),
});
and
case 10:
return AttributeSet::get(C, {
Attribute::get(C, Attribute::NoUnwind),
Attribute::get(C, Attribute::ArgMemOnly),
});
A casualty of this change is the intrin-properties.td test, as I
don't think that FileCheck allows matching this kind of output.

Adding a test for the new lib name combination that this allows, but
also adding a few negative tests for combinations that aren't
matched when -static is specified (because this change in itself
didn't break any of the existing tests either).
The logic in how ld.bfd looks for various libraries based on
an -l<libname> argument is rather complex; the
ldemul_open_dynamic_archive function looks for various combinations:
