sra@google.com ce4b15c0e9 Esoteric bit operations. 
- bit length
- truncate to signed fixed width integer
- truncate to unsigned fixed width integer

This change is motivated by a program that spends 20-30% of its time here:
    // TODO(5828): Replace this with a bit-length method on int when available.
    int n_bitLength = this.n.toRadixString(2).length;

fschneider@google.com cfab482b84 Follow-up fix to my change to IsPowerOfTwo: Alignment of one means no alignment, not zero. 
We assert that the alignment is a power of two. Therefore, platforms that do not need 
alignment should return alignment of one instead of zero.

fschneider@google.com 6632f191c4 Support for unboxed 64-bit integer bitwise operations and equality on ia32. 
This CL adds AND, OR, XOR and == operations on unboxed 64-bit integers
(aka. mints).

Unboxed mints are stored in xmm registers. Each xmm register location
has an additional bit to keep track of its value representation.

Unboxed mints are materialized on the heap on deoptmization in the same way as
unboxed doubles.

The SSE instructions used are available on all CPUs that support SSE 4.1.
