Clement Courbet cc61c822e0 [llvm-exegesis] Support analyzing results from a different target.
We were using the native triple to parse the benchmarks. Use the triple
from the benchmarks file.

Right now this still only allows analyzing files produced by the current
target until D133605 is in.

This also makes the `Analysis` class much less ad-hoc.

Reid Kleckner 89b57061f7 Move TargetRegistry.(h|cpp) from Support to MC
This moves the registry higher in the LLVM library dependency stack.
Every client of the target registry needs to link against MC anyway to
actually use the target, so we might as well move this out of Support.

This allows us to ensure that Support doesn't have includes from MC/*.

Tom Stellard dbefcde6da Merge all the llvm-exegesis unit tests into a single binary
These tests access private symbols in the backends, so they cannot link
against libLLVM.so and must be statically linked.  Linking these tests
can be slow and with debug builds the resulting binaries use a lot of
disk space.

By merging them into a single test binary means we now only need to
statically link 1 test instead of 6, which helps reduce the build
times and saves disk space.

Nico Weber ba7a92c01e [Support] Don't include VirtualFileSystem.h in CommandLine.h
CommandLine.h is indirectly included in ~50% of TUs when building
clang, and VirtualFileSystem.h is large.

(Already remarked by jhenderson on D70769.)

No behavior change.

Dan Gohman 698c6b0a09 [WebAssembly] Support single-floating-point immediate value
As mentioned in TODO comment, casting double to float causes NaNs to change bits.
To avoid the change, this patch adds support for single-floating-point immediate value on MachineCode.

Patch by Yuta Saito.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
