add65451fd Add fpa regression test for fp.to_real denormal encoding fix 
Adds src/test/fpa.cpp with test_fp_to_real_denormal() exercising the
bug reported in the issue: denormal floating-point values in
(_ FloatingPoint 2 24) were getting wrong fp.to_real values because
mk_to_real was not subtracting the normalization shift lz from the
exponent.

Tests verify:
- The specific denormal from the bug report is NOT > 1.0
- Two other denormals have correct real values (0.5 and 0.125)
- A normal value is correctly identified as > 1.0

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.
