library/lexer.m:
Merge the 'integer' and 'big_integer' tokens and extend them to include
signedness and size information. This conforms to recent changes to
the rest of the system and is another step towards supporting additional
types of integer literal.

Update these expected outputs.
In preparation for supporting uint literals and literals for the fixed size
integer types, generalise the representation of integers in the term module, so
that for every integer literal we record its base, value (as an arbitrary
precision integer), signedness and size (the latter two based on the literal's
suffix or lack thereof).
Have the lexer attach information about the integer base to machine sized ints;
we already did this for the 'big_integer' alternative but not the normal one.
In conjunction with the first change, this fixes a problem where the compiler
was accepting non-decimal integers in like arity specifications. (The
resulting error messages could be improved, but that's a separate change.)
Support uints in more places; mark other places which require further work with
XXX UINT.
library/term.m:
Generalise the representation of integer terms so that we can store
the base, signedness and size of a integer along with its value.
In the new design the value is always stored as an arbitrary precision
integer so we no longer require the big_integer/2 alternative; delete it.
Add some utility predicates that make it easier to work with integer terms.
library/term_conversion.m:
library/term_io.m:
Conform to the above changes,
Add missing handling for uints in some spots; add XXX UINT comments
in others -- these will be addressed later.

The lexer was not allowing underscores between leading zeros in decimal integer
literals and float literals (e.g. 0_0 or 0_0.0).

Allow underscores in the above cases.

Announce the addition of support for underscores in numeric literals.

referring to numeric literals in error messages.
