de3cf18899 Fix fp.to_real encoding for denormal floating-point values 
The mk_to_real function in fpa2bv_converter.cpp was missing the
normalization shift adjustment (lz) when computing the real-valued
exponent for denormal floating-point numbers.

When unpack(x, sgn, sig, exp, lz, normalize=true) normalizes a denormal
by shifting the significand left by lz positions, the returned exp does
not account for this shift. All other callers (mk_mul, mk_div, mk_fma)
correctly subtract lz from the exponent, but mk_to_real was missing this.

The fix subtracts zero-extended lz from the sign-extended exp to get the
true exponent, matching the convention used by other FP operations.

Fixes incorrect model with (_ FloatingPoint 2 24) and fp.to_real.
