0ff2c7fe6f Faster Integer.sqrt for large bignum 
Integer.sqrt uses Newton's method.
This pull request reduces the precision which was unnecessarily high in each calculation step.

d4f3dcf4df Refactor VM root modules 
This `st_table` is used to both mark and pin classes
defined from the C API. But `vm->mark_object_ary` already
does both much more efficiently.

Currently a Ruby process starts with 252 rooted classes,
which uses `7224B` in an `st_table` or `2016B` in an `RArray`.

So a baseline of 5kB saved, but since `mark_object_ary` is
preallocated with `1024` slots but only use `405` of them,
it's a net `7kB` save.

`vm->mark_object_ary` is also being refactored.

Prior to this changes, `mark_object_ary` was a regular `RArray`, but
since this allows for references to be moved, it was marked a second
time from `rb_vm_mark()` to pin these objects.

This has the detrimental effect of marking these references on every
minors even though it's a mostly append only list.

But using a custom TypedData we can save from having to mark
all the references on minor GC runs.

Addtionally, immediate values are now ignored and not appended
to `vm->mark_object_ary` as it's just wasted space.

fd87259a26 Replace assert with RUBY_ASSERT in numeric.c 
assert does not print the bug report, only the file and line number of
the assertion that failed. RUBY_ASSERT prints the full bug report, which
makes it much easier to debug.

0c3593b657 Use free with ruby_dtoa 
In ae0ceafb0c0d05cc80623b525070255e3abb34ef ruby_dtoa was switched to
use malloc instead of xmalloc, which means that consumers should be
using free instead of xfree. Otherwise we will artificially shrink
oldmalloc_increase_bytes.

803a072630 Improve performance of Integer#ceildiv 
This patch is suggested by nobu.

Benchmark result:

```
require 'benchmark'

n = 10 ** 7

Benchmark.bm do |x|
  x.report("Fixnum/Fixnum") { a, b = 5, 2; n.times { a.ceildiv(b) } }
  x.report("Bignum/Bignum") { a, b = 10**100, 10**99 - 1; n.times { a.ceildiv(b) } }
  x.report("Bignum/Fixnum") { a, b = 10**100, 3; n.times { a.ceildiv(b) } }
end
```
