Fix type derivation of the exponent for DECODE-FLOAT.

The minimum exponent is from 0, it's from least-positive float.

* src/compiler/float-tran.lisp: * Derive the correct minimum exponent by using the exponent from the least-positive float value of the appropriate type. * tests/float-tran.lisp: * Add tests for the derived exponent type for DECODE-FLOAT.

Conflicts: tests/float-tran.lisp

Fix error in type derivation for the sign in DECODE-FLOAT.

Type derivation of the sign of (DECODE-FLOAT X) returned the incorrect value when x was declared to be of type (DOUBLE-FLOAT (0d0)).

* src/compiler/float-tran.lisp * Fix type derivation * tests/float-tran.lisp * New file for tests of DECODE-FLOAT-SIGN-DERIVE-TYPE-AUX. * tests/float.lisp * New file to test that decode-float is compiled correctly.
