[LTO] Fix commons handling
Previously the prevailing information was not honored, and commons

propose the following semantic for commons: the client should mark
as prevailing the commons that it expects the LTO implementation to

It implies that commons are allowed to have multiple prevailing

[Stackmap] Added callsite counts to emitted function information.
Summary:
It was previously not possible for tools to use solely the stackmap
information emitted to reconstruct the return addresses of callsites in
the map, which is necessary to use the information to walk a stack. This
patch adds per-function callsite counts when emitting the stackmap
section in order to resolve the problem. Note that this slightly alters
the stackmap format, so external tools parsing these maps will need to
be updated.
**Problem Details:**
Records only store their offset from the beginning of the function they
belong to. While these records and the functions are output in program
order, it is not possible to determine where the end of one function's
records are without the callsite count when processing the records to
compute return addresses.

The warning for a format string not being a sting literal and therefore

[OMPT] fix __ompt_get_teaminfo to consult lwt entries of parent teams
The comment already states, that this function should work similarly as __ompt_get_taskinfo.
The function only looked for lwt entries of the current team, but not when unrolling the parents. This fix aligns the implementation to __ompt_get_taskinfo.
The new test case creates a single theaded team (->lwt) and then a nested active team.
Before the innermost print_id(1) would deliver a different team then the outer print_id(0).

[OMPT] Reset task exit frame when execution is finished
The exit address is set when execution of a task is started and should be reset as soon as the execution is finished.
Especially for the asm implementation of __kmp_invoke_microtask, resetting in this call would be painfull, so reset just after the invokation.
The testcase shows the effect of this patch:
Before, the implicit barriers at the end of an implicit task would see an exit address for the implicit task.
This barrier is a task scheduling point. Thus, any explicit task scheduled there would see an exit, but no reenter address for the implicit task.

The latest OMPT spec changed the semantic of a tasks reenter frame to be the application frame, that will be entered, when the runtime frame drops.

[cmake] Support overriding llvm-config query results
Support overriding LLVM_* variables obtained from llvm-config when doing
stand-alone builds. The override of LLVM_MAIN_SRC_DIR is necessary to
provide LLVM sources when the initial directory used to build LLVM does
no longer exist when compiler-rt is built stand-alone. This is
especially the case when building the projects separately in temporary
directories with unpredictable names.
The code is based on existing CMakeLists.txt from clang. Alike clang, it

Two replacements are considered order-independent if one of the following conditions is true:
- They do not overlap. (This is already supported.)
- One replacement is insertion, and the other is a replacement with
length > 0, and the insertion is adjecent to but not contained in the
other replacement. In this case, the replacement should always change
the original code instead of the inserted text.

Perform copying to created arrays according to the packing transformation
This is the fourth patch to apply the BLIS matmul optimization pattern on matmul
kernels (http://www.cs.utexas.edu/users/flame/pubs/TOMS-BLIS-Analytical.pdf).
BLIS implements gemm as three nested loops around a macro-kernel, plus two
packing routines. The macro-kernel is implemented in terms of two additional
loops around a micro-kernel. The micro-kernel is a loop around a rank-1
(i.e., outer product) update. In this change we perform copying to created
arrays, which is the last step to implement the packing transformation.
