RISCVRegisterInfo.h is part of the CodeGen layer. The Utils library
is intended to be shared with the MC layer so shouldn't use files
from the CodeGen layer.
The register enum names are already available from
RISCVMCTargetDesc.h. It appears what was coming from this include
was a transitive include of the Register class which I've replaced
with MCRegister. Register has a constructor from MCRegister so it
should be convertible.
I finally see why this test is failing (on now 2 bots). Somehow the path
name is getting messed up, and the "linux" converted to "1". I suspect
there is something in the environment causing the macro expansion in the
test to get messed up:

On the avr bot:
-DPROFILE_NAME_VAR="/home/buildbot/llvm-avr-linux/llvm-avr-linux/stage1/projects/compiler-rt/test/memprof/X86_64LinuxConfig/TestCases/Output/log_path_test.cpp.tmp.log2"
after macros expansions becomes:

Similar (s/linux/1/) on the other bot.
Disable it while I investigate
By setting up the AsmStrings correctly we can remove some special cases

After 81f7b96ed0, I can see that the
reason this test is failing on llvm-avr-linux is that it doesn't think
the directory exists (error comes during file open for write command).
Not sure why since this is the main test Output directory and we created
a different file there earlier in the test from the same file open
invocation. Print directory contents in an attempt to debug.
When passing -lto-embed-bitcode=post-merge-pre-opt, we were getting
empty .llvmcmd sections. It turns out that is because the
CodeGenOptions::CmdArgs field was only populated when clang saw
-fembed-bitcode={all|marker}.
This patch always populates the CodeGenOptions::CmdArgs. The overhead
of carrying through in memory in all cases is likely negligible in
the grand schema of things, and it keeps the using code simple.

Linalg "tile-and-fuse" is currently exposed as a Linalg pass "-linalg-fusion" but only the mechanics of the transformation are currently relevant.
Instead turn it into a "-test-linalg-greedy-fusion" pass which performs canonicalizations to enable more fusions to compose.
This allows dropping the OperationFolder which is not meant to be used with the pattern rewrite infrastructure.

This fixes an flakyness is all gdb-remote tests. These tests have been
(mildly) flaky since we started using "localhost" instead of 127.0.0.1
in the test suite. The reason is that lldb-server needs to create two
sockets (v4 and v6) to listen for localhost connections. The algorithm
it uses first tries to select a random port (bind(localhost:0)) for the
first address, and then bind the same port for the second one.
The creating of the second socket can fail as there's no guarantee that
port will be available -- it seems that the (linux) kernel tries to
choose an unused port for the first socket (I've had to create thousands
of sockets to reproduce this reliably), but this can apparantly fail
when the system is under load (and our test suite creates a _lot_ of
sockets).
The socket creationg operation is considered successful if it creates at
least one socket is created, but the test harness has no way of knowing
which one it is, so it can end up connecting to the wrong address.
I'm not aware of a way to atomically create two sockets bound to the
same port. One way to fix this would be to make lldb-server report the
address is it listening on instead of just the port. However, this would
be a breaking change and it's not clear to me that's worth it (the
algorithm works pretty well under normal circumstances).
Instead, this patch sidesteps that problem by using "reverse"
connections. This way, the test harness is responsible for creating the
listening socket so it can pass the address that it has managed to open.
It also results in much simpler code overall.
To preserve test coverage for the named pipe method, I've moved the
relevant code to a dedicated test. To avoid original problem, this test
passes raw addresses (as obtained by getaddrinfo(localhost)) instead of
"localhost".
