This update adds upstream patches 8 and 9 to the build:

• The mpfr_digamma function may have an erratic behavior in some cases (an assertion failure in debug mode) when the reflection formula is used, i.e. when x < 1/2. This is fixed by the digamma-interm-zero2 patch (with testcase).
• The Bessel functions (mpfr_j0, mpfr_j1, mpfr_jn, mpfr_y0, mpfr_y1, mpfr_yn) may have an erratic behavior in some cases (an assertion failure in debug mode) when the asymptotic expansion is needed. This is fixed by the jyn_asympt-interm-zero patch (with testcase).
