This patch is a fix to r252901 which changed the behavior of
clang driver. In the presence of "-nostdlib" none of the standard
libraries should be passed to link line.

This more closely matches their locations as described by Intel
documentation, and lets us remove a pair of redundant typedefs.

Summary:
This patch implements the 4.5 specification for the implicit data maps. OpenMP 4.5 specification changes the default way data is captured into a target region. All the non-aggregate kinds are passed by value by default. This required activating the capturing by value during SEMA for the target region. All the non-aggregate values that can be encoded in the size of a pointer are properly casted and forwarded to the runtime library. On top of fixing the previous weird behavior for mapping pointers in nested data regions (an explicit map was always required), this also improves performance as the number of allocations/transactions to the device per non-aggregate map are reduced from two to only one - instead of passing a reference and the value, only the value passed.
Explicit maps will be added later on once firstprivate, private, and map clauses' SEMA and parsing are available.

The host libstdc++ may be horribly broken and we want the fake one to be
picked up. This workaround is lame but I don't see a better way.

OpenMP 4.5 defines new clause 'priority' for 'task', 'taskloop' and 'taskloop simd' directives. Added parsing and sema analysis for 'priority' clause in 'task' and 'taskloop' directives.

Use undefined instead of setzero as the pass through input since its going to be fully overwritten. Use cmpeq of two zero vectors to produce the all 1s vector. Casting -1 to a double and vectorizing causes a constant load of a -1.0 floating point value.

Function types can be extracted from member pointer types.
However, the type is not appropriate without first adjusting the calling
convention.
This fixes PR25661.

Add/Subtract.
The following instructions are added to AArch32 instruction set:
- VQRDMLAH: Vector Saturating Rounding Doubling Multiply Accumulate
Returning High Half
- VQRDMLSH: Vector Saturating Rounding Doubling Multiply Subtract
Returning High Half
The following instructions are added to AArch64 instruction set:
- SQRDMLAH: Signed Saturating Rounding Doubling Multiply Accumulate
Returning High Half
- SQRDMLSH: Signed Saturating Rounding Doubling Multiply Subtract
Returning High Half
This patch adds intrinsic and ACLE macro support for these instructions,
as well as corresponding tests.

handling is corrected, the primary reason for forcing IAS as default is
gone and the remaining issues are still somewhat problematic in common
situations.
