Gabriel Scherer e348103ab8 parsetree.{row,object}_field: move attributes in the wrapper record 
The concrete syntax only allows attributes on tags/constructors/fields
(Rtag, Otag), not on inherited subtypes (Rinherit, Oinherit); we add
this as new enforced invariant in ast_invariants.

Gabriel Scherer 85785b173a parsetree: make sure that all nodes that store attributes also store a location 
Florian Angeletti and myself ran into a problem when trying to use attributes
for ellision of parts of manual example. We wanted to be turn any ast-node
marked with the [@ellipsis] attribute into "..." in the rendering of the
corresponding code block, but for this we need the location of the
attributed node, and it turns out that some constructions supported
attributes without carrying a location:
- Rtag in row_field
- Otag in object_field
- type_exception record
- type_extension record

We added locations in all those positions, guaranteeing the invariant
that all nodes to which attributes can be attached have a precise
position.

octachron 96806cf633 GPR#187: local open for patterns 
This commits extends the pattern syntax to support local open in
patterns. Four new constructions mirroring the expression constructions
are added

    * `M.(pattern)`
    * `M.[pattern_list]` ⟺ M.([pattern_list])
    * `M.{labeled_pattern_list}` ⟺ M.({label_pattern_list})
    * `M.[| .. |] ⟺ M.( [| .. |] )

At the typing phase, the construction `M.(pattern)` brings all
identifiers defined within M inside the scope and then proceed with the
typing of `pattern`. All others constructions are desugared to the
`M.(..)` construction during parsing.

Questionable implementation details:
* Currently, the local pattern open use the `type_open` function like
the local expression pattern. However, this implies that values defined
inside `M` are also brought to the scope. A specialized
`type_open_for_pattern` would be more efficient.

Hugo Heuzard 9eca3e4519 Parse arbitrary precision integers .. 
.. and allow any letter in [g-zG-Z] as modifier (previously 'l','L','n')
Also allow modifier for floats
This give more freedom to ppx rewritters (what about a ppx for zarith)

Checks are performed when translating from Parsetree to Typedtree.
Invalid_literal is raised if the modifier is not recognized ([lLn]?)
Integer_overflow is raised as before.

Lexer: use g-zG-Z for integer literal modifier

Lexer: Allow modifier on float

Clean wrt previous commits

Lexer: use named substring

since a constant does not always correspond to exactly one token, so
there is no point in making the AST more complex.
