Jonathan Peyton 7f976d556a Fix memory error in case of reinit using kmp_set_defaults() for lock code.
The lock tables were being reallocated if kmp_set_defaults() was called.
In the env_init code it says that the user should be able to switch between
different KMP_CONSISTENCY_CHECK values which is what this change enables.

Jonathan Peyton d0365a228c Fix small memory leak regarding __kmp_nested_proc_bind
There is no corresponding free() for this expandable array.  The logic is
added in __kmp_cleanup() next to the freeing of __kmp_nested_nth.

Eric Fiselier 337a7c542d Fix filesystem::path assignment from {}
Adding `path::operator=(string_type&&)` made the expression `p = {}`
ambiguous. This path fixes that ambiguity by making the `string&&`
overload a template so it ranks lower during overload resolution.

These two are independent: it's possible to use LLD without LTO,
and it's possible to do LTO build without LLD.

This patch adds a test for an invalid output path for -Map option,
though that test is not for verifying that we are using error()
instead of fatal() in writeMapFile.

Chandler Carruth 88c36d7852 [LoopDeletion] (cleanup, NFC) Make this test actually test what it
claims to test.

LoopSimplify was unifying the multiple exits in this test case, making
it never even test the multiple exit handling of LoopDeletion. Doh.

Now it works (thanks to a great idea from mkuper) and will fail if we
ever change something to make it stop working.

Eric Fiselier f744e7e15a [LIT] Make util.executeCommand python3 friendly
Summary: The parameter `input` to `subprocess.Popen.communicate(...)` must be an object of type `bytes` . This is strictly enforced in python3. This patch (1) allows `to_bytes` to be safely called redundantly. (2) Explicitly convert `input` within `executeCommand`. This allows for usages like `executeCommand(['clang++', '-'], input='int main() {}\n')`.

Justin Lebar cc938fc197 [NVPTX] Implement min/max in tablegen, rather than with custom DAGComine logic.
Summary:
This change also lets us use max.{s,u}16.  There's a vague warning in a
test about this maybe being less efficient, but I could not come up with
a case where the resulting SASS (sm_35 or sm_60) was different with or
without max.{s,u}16.  It's true that nvcc seems to emit only
max.{s,u}32, but even ptxas 7.0 seems to have no problem generating
efficient SASS from max.{s,u}16 (the casts up to i32 and back down to
i16 seem to be implicit and nops, happening via register aliasing).

In the absence of evidence, better to have fewer special cases, emit
more straightforward code, etc.  In particular, if a new GPU has 16-bit
min/max instructions, we want to be able to use them.

Summary:
Avoid an unnecessary conversion operation when using the result of
ctpop.i32 or ctpop.i16 as an i32, as in both cases the ptx instruction
we run returns an i32.

(Previously if we used the value as an i32, we'd do an unnecessary
zext+trunc.)

The patch is to solve the performance problem described in PR27827.
Register coalescing sometimes cannot remove a copy because of interference.
But if we can find a reverse copy in one of the predecessor block of the copy,
the copy is partially redundent and we may remove the copy partially by moving
it to the predecessor block without the reverse copy.
