Alexander Kornienko 21de0ae3d4 Re-apply "r226548 - Introduce SPIR calling conventions" reverted in r226558.
The test was fixed after a discussion with the revision author: the check
pattern was made more flexible as the "%call" part is not what we actually want
to check strictly there.

The original patch description:
===
Introduce SPIR calling conventions.

This implements Section 3.7 from the SPIR 1.2 spec:

    SPIR kernels should use "spir_kernel" calling convention.
    Non-kernel functions use "spir_func" calling convention. All
    other calling conventions are disallowed.

The patch works only for OpenCL source. Any other uses will need
to ensure that kernels are assigned the spir_kernel calling
convention correctly.
