[Clang][Driver] Re-use the calling process instead of creating a new
process for the cc1 invocation
With this patch, the clang tool will now call the -cc1 invocation
directly inside the same process. Previously, the -cc1 invocation was
creating, and waiting for, a new process. This patch therefore reduces
the number of created processes during a build, thus it reduces build
times on platforms where process creation can be costly (Windows) and/or
impacted by a antivirus. It also makes debugging a bit easier, as
there's no need to attach to the secondary -cc1 process anymore,
breakpoints will be hit inside the same process.
Crashes or signaling inside the -cc1 invocation will have the same
side-effect as before, and will be reported through the same means.
This behavior can be controlled at compile-time through the
CLANG_SPAWN_CC1 cmake flag, which defaults to OFF. Setting it to ON will
revert to the previous behavior, where any -cc1 invocation will
create/fork a secondary process. At run-time, it is also possible to
tweak the CLANG_SPAWN_CC1 environment variable. Setting it and will
override the compile-time setting. A value of 0 calls -cc1 inside the
calling process; a value of 1 will create a secondary process, as
before.

[mlir][Linalg] Update ReshapeOp::build to be more idiomatic
Summary: This diff makes it easier to create a `linalg.reshape` op and
adds an EDSC builder api test to exercise the new builders.
