[PATCH/ARM] To fix vcvt bug.

["Sameera Deshpande" <sameera dot deshpande at arm dot com>]

Hi!

This patch adds check for range of the immediate operand in instruction
`vcvt' between floating point and fixed point.
If the type size of fixed point number is 16, the immediate value should be
in range [ 0, 16].
For 32 bit size, the immediate value should be in range [1, 32].

Tested using make check without regression.
