Fixed extraction of [match] the presence of some ghost branches.
It must be the case that all brunches return [unit] and at least one of the
non-ghost ones must be effectful.

Formerly we only parsed elements of float values as decimals when they can
be hexadecimal.

* src/driver/parse_smtv2_model_lexer.mll
(float_num): Now takes hexadecimal number instead of decimal numbers.

This commit adds parsing for boolean expression and floating point value
which are returned by z3 on the last version. This adds floating point
values in the collected data and JSON printed data. This does not add
boolean expressions because it does not add information.
Also added transformation eliminate epsilon in driver for Z3 ce.

* drivers/z3_gnatprove_ce.drv
(eliminate_epsilon): Added transformation eliminate epsilon in driver for
counterex for z3.

* src/core/model_parser.ml
(float_type): Added a float_type and functions to send it as JSON data.

* src/driver/collect_data_model.ml
(convert_array_value): Explicit matching for error handling when adding
constructs.
(convert_float): Dummy conversion of float_type to avoid circular
dependency.

* src/driver/parse_smtv2_model_lexer.mll
(token): Adding z3 specific boolean expressions. Also adding a way to
parse all floating point value including those we don't want to print
because we need to parse them even if we don't want to print them.

* src/driver/parse_smtv2_model_parser.mly
(smt_term): Adding floating point value case which is handled in the lexer.
Added boolean_expression case.

* src/driver/smt2_model_defs.ml
(float_type): Adding a duplicated float_type for dependencies reasons.
(print_float): Debugging print of float_type.
(): Adding cases for float in remaining functions.

This commits allows printing of arrays which have indices typed as
bitvectors.

* src/driver/collect_data_model.ml
(convert_to_indice): Add bitvector case.
