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

Fixes processing of declarative directives and standalone executable directives. Declarative directives should not be allowed as an immediate statements and standalone executable directives are allowed to be used in case-stmt constructs.

Currently, when there is a global register variable in a program that
is bound to an invalid register, clang/llvm prints an error message that
is not very user-friendly.
This commit improves the diagnostic and moves the check that used to be
in the backend to Sema. In addition, it makes changes to error out if
the size of the register doesn't match the declared variable size.
e.g., volatile register int B asm ("rbp");

-fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

Codegen for threadprivate variables (and in some other cases) may cause crash of the compiler if some diagnostic is produced later. This happens because some of the autogenerated globals are not removed from InternalVars StringMap when llvm::Module is reset.

For namespaces, this is consistent with mangling and GCC's debug info
behavior. For structs, GCC uses <anonymous struct> but we prefer
consistency between all anonymous entities but don't want to confuse
them with template arguments, etc, so we'll just go with parens in all
cases.

Move some of the verifier directives away from the end of the pragma line.
This ensures that the diagnostics relate to the trailing token being tested and
not the verifier comments which are themselves part of the token stream.

The recovery was failing due to a missing case in SkipUntil().
Also add back tests from r197553 that were reverted in the previous commit.
llvm-svn: 197598
These parser changes were redundant. The same or better recovery can be
achieved with a one-line fix to SkipUntil() due to land in the next commit.
This reverts commit r197553.
