Summary:
Added basic analysis of map clauses. Only map clauses with to and tofrom
map type must be analyzed since all other map types (alloc, delete, etc.) do not require to use the value of the initial variable, instead they create the new copy of the variable.

only.
Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.

According to OpenMP 5.0 at least one 'map' or 'use_device_ptr' clause
must be specified for 'target data' construct. Patch adds support for
this feature.

Summary: The map modifier 'delete' is parser in c++ mode as a delete keyword, which requires special handling in the map clause parsing.

Support for the following OpenMP 4.5 restriction on 'target enter data' and 'target exit data':
- A map-type must be specified in all map clauses.
I have to save 'IsMapTypeImplicit' when parsing a map clause to support this constraint and for more informative error messages. This helps me support the following case:
#pragma omp target enter data map(r) // expected-error {{map type must be specified for '#pragma omp target enter data'}}
and distinguish it from:
#pragma omp target enter data map(tofrom: r) // expected-error {{map type 'tofrom' is not allowed for '#pragma omp target enter data'}}
Patch by Arpith Jacob. Thanks!
