This is only used for calculating ConcatLen. This isn't necessary,
since it's easily derived from the traversal setting suffix indices.

Remove that. Rename CurrIdx to CurrNodeLen to better describe what's
going on.

Summary:
The DAP on vscode uses a JavaScript `number` for identifiers while the
Visual Studio version uses a C# `Int` for identifiers. lldb-vscode is
bit shifting identifiers 32 bits and then bitwise ORing another 32 bit
identifier into a 64 bit id to form a unique ID. Change this to
a a partitioning of the 32 bits that makes sense for the data types.

This takes the traversal methods introduced in r346269 and adapts them
into an iterator. This allows the outliner to iterate over repeated substrings
within the suffix tree directly without having to initially find all of the
substrings and then iterate over them after you've found them.

Summary:
This patch introduces a CodeRegionGenerator class which is responsible for parsing some type of input and creating a 'CodeRegions' instance for use by llvm-mca.  In the future, we will also have a CodeRegionGenerator subclass for converting an input object file into CodeRegions.  For now, we only have the subclass for converting input assembly into CodeRegions.

This is mostly a NFC patch, as the logic remains close to the original, but now encapsulated in its own class and moved outside of llvm-mca.cpp.

NFC-ish. This doesn't change the behaviour of the outliner, but does make sure
that you won't end up with say

OUTLINED_FUNCTION_2:
...
ret

OUTLINED_FUNCTION_248:
...
ret

as the only outlined functions in your module. Those should really be

OUTLINED_FUNCTION_0:
...
ret

OUTLINED_FUNCTION_1:
...
ret

If we produce outlined functions, they probably should have sequential numbers
attached to them. This makes it a bit easier+stable to write outliner tests.

The point of this is to move towards a bit more stability in outlined function
names. By doing this, we at least don't rely on the traversal order of the
suffix tree. Instead, we rely on the order of the candidate list, which is
*far* more consistent. The candidate list is ordered by the end indices of
candidates, so we're more likely to get a stable ordering. This is still
susceptible to changes in the cost model though (like, if we suddenly find new
candidates, for example).

llvm-svn: 346340

We have seen failing builds due to a race condition between
RTAsan_dynamic and libc++ headers builds, specifically libc++
headers depend on __config and if this header hasn't been copied
into the final location, including other headers will typically
result in failure. To avoid this race, we add an explicit dependency
on libc++ headers which ensures that they've been copied into place
before the sanitizer object library build starts.

[GCOV] Flush counters before to avoid counting the execution before fork twice and for exec** functions we must flush before the call

Summary:
This is replacement for patch in https://reviews.llvm.org/D49460.
When we fork, the counters are duplicate as they're and so the values are finally wrong when writing gcda for parent and child.
So just before to fork, we flush the counters and so the parent and the child have new counters set to zero.
For exec** functions, we need to flush before the call to have some data.
