Ramkumar Ramachandra 4a9aef683d DynamicAPInt: optimize size of structure (#97831) ...

Reuse the APInt::BitWidth to eliminate DynamicAPInt::HoldsLarge, cutting
the size of DynamicAPInt by four bytes. This is implemented by making
DynamicAPInt a friend of SlowDynamicAPInt and APInt, so it can directly
access SlowDynamicAPInt::Val and APInt::BitWidth.

We get a speedup of 4% with this patch.
