Don't assume long long == 8 bytes.
If you can assume C99, there are macros named UINT64_C and
such for appropriate integer literal suffixes.
If you can't, no way but do a bitwise or.

Use ALLOCV to allocate struct crypt_data for slightly cleaner and less
error-prone code. It is currently possible it leaks when an invalid
argument is passed to String#crypt or rb_str_new_cstr() fails to
allocate memory.
SIZEOF_CRYPT_DATA macro in missing/crypt.h is removed since it is not
used any longer.

This patch will add pre-allocation in string interpolation.
By this, unecessary capacity resizing is avoided.
For small strings, optimized `rb_str_resurrect` operation is
faster, so pre-allocation is done only when concatenated strings
are large. `MIN_PRE_ALLOC_SIZE` was decided by experimenting with
local machine (x86_64-apple-darwin 16.5.0, Apple LLVM version
8.1.0 (clang - 802.0.42)).
String interpolation will be faster around 72% when large string is created.
