This replaces DoNotLinkFromSource with ValuesToLink. It also moves the
computation of ValuesToLink earlier.

It is a bit simpler and an important step in slitting the linker into an
ir mover and a linker proper.

The test change is because we now avoid creating dead declarations.

Having to import an alias as declaration is not thinlto specific.

The test difference are because when we already have a decl and we are
not importing it, we just leave the decl alone.

AggressiveAntiDepBreaker was renaming registers specified by the user
for inline assembly. While this will work for compiler-specified
registers, it won't work for user-specified registers, and at the time
this runs, I don't currently see a way to distinguish them.

Try a test run with something like this to check out the new
basic results formatter (not used by default):

time test/dotest.py --executable `pwd`/build/Debug/lldb --results-formatter lldbsuite.test.basic_results_formatter.BasicResultsFormatter --results-file stdout

This will yield something like:

The Details header only prints if there are any issues to report.  The
Details section has tags that should get picked up using the normal
issue text scrapers (e.g. buildbot).

Test numbers reported are strictly test method runs.

The rerun bit at the top is in support of the multi-pass test
runner code (to run the low-load, single worker test pass for
tests that failed the first run), which I'll be able to put up
for review after this.

ResultsFormatters now have the ability to indicate they replace
the legacy summary, as this one does.

Once we come to agreement on the exact format, I will switch
us over to using this by default.

vector.resize() is significantly slower than memset in many STLs
and the cost of initializing these vectors is significant on targets
with many registers. Since we don't need the overhead of a vector,
use a simple unique_ptr instead.

Summary: This changes overflow handling during instrumentation profile merge. Rathar than throwing away records that would result in counter overflow, merged counts are instead clamped to the maximum representable value. A warning about counter overflow is still surfaced to the user as before.

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.
