0595ab3eef ocl: fix usage of invalid OpenCL cache on mixed 64/32-bit platforms 
Observed during launch of 32/64-bit applications on Windows.
Added '32-bit' prefix for 32-bit OpenCL devices. No prefix on 64-bit configurations.

0ed3209b00 ocl: avoid unnecessary loading/initializing OpenCL subsystem 
If there are no OpenCL/UMat methods calls from application.

OpenCL subsystem is initialized:
- haveOpenCL() is called from application
- useOpenCL() is called from application
- access to OpenCL allocator: UMat is created (empty UMat is ignored) or UMat <-> Mat conversions are called

Don't call OpenCL functions if OPENCV_OPENCL_RUNTIME=disabled
(independent from OpenCL linkage type)

2610a47c89 core:ppc Fix 2 interleave logic errors in vsx_utils.hpp 
When elements are 64 bits, the vec_st_interleave()/vec_ld_deinterleave()
doesn't interleave 4 elements correctly.

For vec_st_interleave(), following is saved into mem:
	a0 b0 a1 b1 c0 d0 c1 d1
     -> we expected:
	a0 b0 c0 d0 a1 b1 c1 d1

for vec_ld_deinterleave(), following is loaded into a b c d for memory
string { 1 2 3 4 5 6 7 8 }:
	a: 1 3
	b: 2 4
	c: 5 7
	d: 6 8
   -> we expected:
   	a: 1 5
	b: 2 6
	c: 3 7
	d: 4 8

This patch corrects this behavior.
