WISH: possibility to enquire the element properties of vector! values

[Siskin-Bot]

Submitted by: Oldes

vector! values have an element type (integer! and decimal! so far) and a bit-size (8 16 32 or 64). Integers also may be unsigned. Currently the only way to find the actual properties from a given vector value is to mold the value and parse the resulting string.

Above commit should be enough for accessing vector properties. I'm just not sure with the length. Now it reports complete length (not counting with possibly changed index:

>> spec-of probe make vector! [integer! 8 4]
make vector! [integer! 8 4 [0 0 0 0]]
== [integer! 8 4]

>> spec-of probe skip make vector! [integer! 8 4] 2
make vector! [integer! 8 2 [0 0]]
== [integer! 8 4]

versus:

>> length? make vector! [integer! 8 4]
== 4

>> length? skip make vector! [integer! 8 4] 2
== 2

Is it ok?
