.. 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

Translate [%ocaml.extension_constructor <path>] to the
runtime-representation of the extension constructor denoted by
<path>. This allows one to get the extension constructor without
having to create a dummy value.
From comments in typedtree.mli:
When introduced in 2000, this [type] enabled a more efficient code
generation for optional arguments. However, today the information is
redundant as labels are passed to [transl_apply] too. Could be cleaned
up.
Merge of branch 'hex-float'.
- Add support in byterun/floats.c for conversions between floats and strings in hex notation. We cannot rely on the C standard library here because Microsoft consistently fails at supporting hex notation as standardized in C99. Instead, the conversions are implemented from scratch.
- Add support in the lexer so that hex float literals are recognized in OCaml sources.
- Add support in formats. The ISO C99 format letters for hex floats are %a and %A, but %a is already taken. I chose %h and %H, which are rejected today as bad formats (hence no backward incompatibility) and don't mean anything in C either (h is a modifier, not a format letter).
- Add support in printf. All the trimmings are there in the implementation of %h and %H, including sign modifier and fixed precision.
- Benoit Vaugon contributed support in scanf.

In PR#6812 garrigue said:
"Note that we do not want to disable visiting of all aliases, but just of
aliases of persistent modules, which is a bit more complex."
Which is not actually quite true, we want to disable visiting aliases of
persistent modules which we haven't already visited.
- float
- int32
- int64
- nativeint
Not for int because the comparison is done directly on the untagged version.
Useful mainly for floats since they can be stored unboxed in records or arrays.
