89b60ffbd4 Refactor error reporting
This commit introduces ErrorReporter, a utility class which consolidates
all of the error logging functionality into a common set of functions.
It also replaces all direct interactions with an ErrorList with calls to
an ErrorReporter.

4524ad0870 Add support for do/while loops
This commit adds support for a standard do <statement> while <expr>;
form of statement.  While loops were already being supported; supporting
a do/while loop mostly involves reusing code from while loops but putting
the conditional checking last.

4337e70cca Prepare for leaky exceptions
Now toFormalType() reports errors by exceptions, they will be
sometimes leaked to the wider context.  This commits adds a catch.

ac7c6ae7d2 toFormalType reports errors by an exception
This allows error reporting without passing `ASTNode` to `toFormalType()`

c861cf579d Translate mapping types into Why3 arrays when keys are integers
Even when the keys are signed the translation is supposed to work
because Why3 arrays allow negative indices.

a98edb22e5 Add Address module in the WhyML prelude
In the `--formal` output, this commit adds a module called `Address`,
which defines the address type as unsigned integer type bounded at
2^160-1.

9a075458ad initial work for fixed types...potentially needing a constant literal type for this
notation

Rational implemented...trying to figure out exponential

fix for token bug, also quick fix for the wei and seconds

fixed problem with var...probably a conversion problem for fixed in size capabilities

adding fixed type tests

Removing bitshift and regrouping fixed type tests together

size capabilities functioning properly for fixed types

got exponents up and working with their inverse, changed a few of the tests....something is working that likely shouldn't be

slight changes to how to flip the rational negative around...still trying to figure it out

tests added

updated tests

odd differences in trying soltest from solc binary, let me know if you can replicate

test not working for odd reason

fixed test problem with fixed literals...still need a way to log this error

broken up the tests, added some, changed some things in types and began compiler work

moar tests and prepping for rebuilding much of the types.cpp file

further fixing

initial work for fixed types...potentially needing a constant literal type for this
