Created attachment 8350

Revised patch including test cases

Added 3 test cases (vfpv2 which has no vmov, vfpv3xd which has only single vmov
and vfpv3 which has both single and double vmov).

Note that while making the patch a problem was discovered: VMOV with immediate
value of -0.125 compiles correctly for single but not for double registers:
vmov s0,#0xbe000000 ; OK
vmov d0,#0xbe000000 ; OK

When this problem will be corrected the test case for vfpv3 will give an error
on that vldr
