Erich Keane 856f3fe5bb Fix always_inline 'target' compatibility check code for Lambdas
The previous version of this used CurFuncDecl in CodeGenFunction,
however this doesn't include lambdas.  However, CurCodeDecl DOES. Switch
the check to use CurCodeDecl so that the actual function being emitted
gets checked, preventing an error in ISEL.

Jonas Devlieghere 3331fd8228 [dotest] Centralize and simplify session dir logic (NFC)
I was looking at the session directory logic for unrelated reasons and
noticed that the logic spread out across dotest. This simplifies things
a bit by moving the logic together.

Julian Lettner 3ae9b9d5e4 [ASan] Make insertion of version mismatch guard configurable
By default ASan calls a versioned function
`__asan_version_mismatch_check_vXXX` from the ASan module constructor to
check that the compiler ABI version and runtime ABI version are
compatible. This ensures that we get a predictable linker error instead
of hard-to-debug runtime errors.

Sometimes, however, we want to skip this safety guard. This new command
line option allows us to do just that.

Jessica Paquette 7080ffa21a [GlobalISel] Import patterns containing SUBREG_TO_REG
Reuse the logic for INSERT_SUBREG to also import SUBREG_TO_REG patterns.

- Split `inferSuperRegisterClass` into two functions, one which tries to use
  an existing TreePatternNode (`inferSuperRegisterClassForNode`), and one that
  doesn't. SUBREG_TO_REG doesn't have a node to leverage, which is the cause
  for the split.

- Rename GlobalISelEmitterInsertSubreg.td to GlobalISelEmitterSubreg.td and
  update it.

- Update impacted tests in the AArch64 and X86 backends.

This is kind of a hit/miss for code size improvements/regressions. E.g. in
add-ext.ll, we now get some identity copies. This isn't really anything the
importer can handle, since it's caused by a later pass introducing the copy for
the sake of correctness.

Artem Dergachev 8b2a39e937 [analyzer] Trust global initializers when analyzing main().
If the global variable has an initializer, we'll ignore it because we're usually
not analyzing the program from the beginning, which means that the global
variable may have changed before we start our analysis.

However when we're analyzing main() as the top-level function, we can rely
on global initializers to still be valid. At least in C; in C++ we have global
constructors that can still break this logic.

This patch allows the Static Analyzer to load constant initializers from
global variables if the top-level function of the current analysis is main().

Johannes Doerfert f7ca0fe1c8 [Attributor] Regularly clear dependences to remove spurious ones
As dependences between abstract attributes can become stale, e.g., if
one was sufficient to imply another one at some point but it has since
been wakened to the point it is not usable for the formerly implied one.
To weed out spurious dependences, and thereby eliminate unneeded
updates, we introduce an option to determine how often the dependence
cache is cleared and recomputed during the fixpoint iteration.

Note that the initial value was determined such that we see a positive
result on our tests.

The purpose of the constrained intrinsics is to force the optimizer to

STDC FENV_ACCESS ON pragma without interfering with optimizations when
these restrictions are not needed.

This patch removes the -q (quiet) flag and changing the default
behavior. Currently the flag serves two purposes that are somewhat
contradictory, as illustrated by the difference between the argument
name (quiet) and the configuration flag (parsable). On the one hand it
reduces output, but on the other hand it prints more output, like the
result of individual tests. My proposal is to guard the extra output
behind the verbose flag and always print the individual test results.

r268231 made it so that the name of the --reproduce archive
is no longer listed in the response file. Previously, with
"--reproduce repro.tar" the response file would contain

  repro/home/.../llvm-build-dir/.../foo.o

but after that change it contained

  home/.../llvm-build-dir/.../foo.o

instead. The test added for this in r268231 checked that
the response file doesn't contain the string "repro", but
if the build dir is named e.g. "llvm-build-repro" then the
test fails because of that.

Change the assert to check that "repro" doesn't exist at the
beginning of the line instead. I verified that the test
still fails with r268231 reverted.

The test technically still fails if someone builds llvm in a directory
'/repro' below the root directory. Don't do that :)
