5739f705ee Use integral constants 
The compiler is smart enough to convert those into double for powerpc,
but if we put them as doubles, it adds overhead by performing those
operations in floating point mode.

6f2e90e78f Make mantissa type of mp_no configurable 
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.

e42a38dd9d BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibm 
The patch increase the high value to check if expl overflows. Current
high mark value is not really correct, the algorithm accepts high values.
It also adds a correct wrapper function to check for overflow and underflow.

4d55b4e596 Add assert for potential access beyond array bounds in m1np 
The mpexp code has an access into m1np:

  for (i=n-1; i>0; i--,n--) { if (m1np[i][p]+m2>0) break; }

which could break for p >= 18 or i >= 7.  Fortunately this code is
never called due to the way the exp function is implemented since
values having exponent less than -55 return 1.0.  Make sure that if it
gets called in future, it is trapped.

89c9aa491a Fix for logb/logbf/logbl (bugs 13954/13955/13956) 
POSIX 2008 states that if the input for 'logb[f|l]' is a subnormal number
it should be treated as if it were normalized.  This means the
implementation should calculate the log2 of the mantissa and add it to the
subnormal exponent (-126 for float and -1022 for double and IBM long
double).  This patch takes care of that.
