Alexey Bataev a8a9153a37 [OPENMP] Support for -fopenmp-simd option with compilation of simd loops 
only.

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

Samuel Antao 1168d63cf9 [OpenMP] Use fopenmp prefix for all options introduced by the offloading implementation. 
Summary: This patch changes the options used by offloading to start with -fopenmp instead of -fomp. This makes the option naming more consistent and materializes a suggestion by Richard Smith in http://reviews.llvm.org/D9888.

Samuel Antao 6d0042642a Re-apply r272900 - [OpenMP] Cast captures by copy when passed to fork call so that they are compatible to what the runtime library expects. 
An issue in one of the regression tests was fixed for 32-bit hosts.

Samuel Antao b1f9501242 Revert r272900 - [OpenMP] Cast captures by copy when passed to fork call so that they are compatible to what the runtime library expects. 
Was causing trouble in one of the regression tests for a 32-bit address space.

Samuel Antao 4951617980 [OpenMP] Cast captures by copy when passed to fork call so that they are compatible to what the runtime library expects. 
Summary:
This patch fixes an issue detected when firstprivate variables are passed to an OpenMP outlined function vararg list. Currently they are not compatible with what the runtime library expects causing malfunction in some targets.

This patch fixes the issue by moving the casting logic already in place for offloading to the common code that creates the outline function and arguments and updates the regression tests accordingly.

Alexey Bataev 7ace49dff1 [OPENMP] Pass scalar firstprivate vars by value. 
For better performance and to unify code with offloading part we pass
scalar firstprivate values by value, instead of by reference. It will
remove some extra copying operations.

Samuel Antao aeb7b539f5 [OpenMP] Replace offloading option that start with -o with -fo. 
Summary:
The current offloading implementation is using -omptargets and -omp-host-ir-file-path options in the frontend. This causes the user a lot of trouble due to to the conflicts with the -o option. E.g. if the user misspells  omptargets he will end up with a file with a weird name.

This patches replaces these two options with  -fomptargets and -fomp-host-ir-file-path to avoid these issues, and it is also more consistent with the other options like -fopenmp.
