[PATCH 0/3] testsuite: Exclude vector tests for unsupported targets

["Maciej W. Rozycki" <macro@embecosm.com>]

Hi,

 In the course of verifying an out-of-tree RISC-V target that has a vendor
extension providing hardware support for vector operations on pairs of 
single floating-point values (similar to MIPS paired-single or Power SPE 
vector types) I have come across a couple of tests that fail just because 
they expect GCC to produce code this particular hardware does not support.  
Therefore I have created this small patch series, which marks the features 
required for the test cases to be relevant, which makes them unsupported 
for the hardware concerned.  For further details see individual change 
descriptions.

 This patch series has been verified with an `x86_64-linux-gnu' native 
configuration.  I could verify it with MIPS paired-single hw sometime, but 
I'm not currently set up for it and I think the changes are obvious enough 
regardless.

 OK to apply?  As testsuite fixes I think the changes also qualify for 
backporting to active release branches.
