[gomp4] PTX target format

I've committed this to gomp4 branch. It changes the ptx target data format from a string array with embedded NULs, to an array of pointers & sizes to separate strings for each object file. This avoids the use of strlen when loading onto the PTX device. Not incrementing the PTX version number

[gomp4] openacc default handling

I've committed this to gomp4. When I broke out the oacc_default_clause function from omp_notice_variable, I was puzzled by the ordering of the lookups, but could quite figure out what was wrong. further investigation and standard reading showed that for openacc, we look in outer lexical scop

[gomp4.1] fold ordered depend(sink) clauses

The attached patch canonicalizes sink dependence clauses into one folded clause if possible (as discussed in the paper "Expressing DOACROSS Loop Dependences in OpenMP"). The basic algorithm is to create a sink vector whose first element is the GCD of all the first elements, and whose remaining
