* add `@bswap` builtin function. See #767 * comptime evaluation facilities are improved to be able to handle a `@ptrCast` with a backing array. * `@truncate` allows "truncating" a u0 value to any integer type, and the result is always comptime known to be `0`. * when specifying pointer alignment in a type expression, the alignment value of pointers which do not have addresses at runtime is ignored, and always has the default/ABI alignment * threw in a fix to freebsd/x86_64.zig to update syntax from language changes * some improvements are pending #863 closes #638 closes #1733 std lib API changes * io.InStream().readIntNe renamed to readIntNative * io.InStream().readIntLe renamed to readIntLittle * io.InStream().readIntBe renamed to readIntBig * introduced io.InStream().readIntForeign * io.InStream().readInt has parameter order changed * io.InStream().readVarInt has parameter order changed * io.InStream().writeIntNe renamed to writeIntNative * introduced io.InStream().writeIntForeign * io.InStream().writeIntLe renamed to writeIntLittle * io.InStream().writeIntBe renamed to writeIntBig * io.InStream().writeInt has parameter order changed * mem.readInt has different parameters and semantics * introduced mem.readIntNative * introduced mem.readIntForeign * mem.readIntBE renamed to mem.readIntBig and different API * mem.readIntLE renamed to mem.readIntLittle and different API * introduced mem.readIntSliceNative * introduced mem.readIntSliceForeign * introduced mem.readIntSliceLittle * introduced mem.readIntSliceBig * introduced mem.readIntSlice * mem.writeInt has different parameters and semantics * introduced mem.writeIntNative * introduced mem.writeIntForeign * mem.writeIntBE renamed to mem.readIntBig and different semantics * mem.writeIntLE renamed to mem.readIntLittle and different semantics * introduced mem.writeIntSliceForeign * introduced mem.writeIntSliceNative * introduced mem.writeIntSliceBig * introduced mem.writeIntSliceLittle * introduced mem.writeIntSlice * removed mem.endianSwapIfLe * removed mem.endianSwapIfBe * removed mem.endianSwapIf * added mem.littleToNative * added mem.bigToNative * added mem.toNative * added mem.nativeTo * added mem.nativeToLittle * added mem.nativeToBig
