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.
Before it was the last frame in the runtime. This doesn't work for some gcc execution pathes or even clang generated code for :
Since there is no runtime frame between the executed task and the encountering task.

The test case compares exit and reenter addresses against addresses captured in application code

OMPT tests can check for right frame information of tasks:
 * parent_task_frame was directly printed as a pointer, but actually points to a struct ompt_frame {void*, void*}
 * NULL is printed in the beginning of execution and loaded to FileChecker variable [[NULL]]
 * implicit tasks now also print their frame information
 * macro to print frame address from application
 * print task info for barrier begin

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
extends the override to all queried variables.

--section-start=sectionname=org
Locate a section in the output file at the absolute address given by org. 
You may use this option as many times as necessary to locate multiple sections in the command line.
 org must be a single hexadecimal integer; for compatibility with other linkers, 
you may omit the leading `0x' usually associated with hexadecimal values. 
Note: there should be no white space between sectionname, the equals sign (“<=>”), and org.

-Tbss=org
-Tdata=org
-Ttext=org
Same as --section-start, with .bss, .data or .text as the sectionname.

Summary:
Extend `tooling::Replacements::add()` to support adding order-independent replacements.

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.

Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. Allowing to use both -qualified-name and -offset at once
while performing efficient renamings seems like a feature, too. Maintaining main
function wrappers and custom help becomes redundant while CLI becomes less
confusing.

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.

Previously, all input files were owned by the symbol table.
Files were created at various places, such as the Driver, the lazy
symbols, or the bitcode compiler, and the ownership of new files
was transferred to the symbol table using std::unique_ptr.
All input files were then free'd when the symbol table is freed
which is on program exit.

I think we don't have to transfer ownership just to free all
instance at once on exit.

In this patch, all instances are automatically collected to a
vector and freed on exit. In this way, we no longer have to
use std::unique_ptr.
