softfloat: Apply patch corresponding to rebasing to softfloat-2a
This commit applies the changes to master which correspond to replacing commit 158142c2c2df with a set of changes made by: * taking the SoftFloat-2a release * mechanically transforming the block comment style * reapplying Fabrice's original changes from 158142c2c2df This commit was created by: diff -u 158142c2c2df import-sf-2a patch -p1 --fuzz 10 <../relicense-patch.txt (where import-sf-2a is the branch resulting from the changes above).
