Oliver Stannard 9181785a0c Add backend dignostic printer for unsupported features
Re-commit of r258950 after fixing layering violation.

The related LLVM patch adds a backend diagnostic type for reporting
unsupported features, this adds a printer for them to clang.

In the case where debug location information is not available, I've
changed the printer to report the location as the first line of the
function, rather than the closing brace, as the latter does not give the
user any information. This also affects optimisation remarks.

Oliver Stannard 7e7d983a87 Refactor backend diagnostics for unsupported features
Re-commit of r258951 after fixing layering violation.

The BPF and WebAssembly backends had identical code for emitting errors
for unsupported features, and AMDGPU had very similar code. This merges
them all into one DiagnosticInfo subclass, that can be used by any
backend.

There should be minimal functional changes here, but some AMDGPU tests
have been updated for the new format of errors (it used a slightly
different format to BPF and WebAssembly). The AMDGPU error messages will
now benefit from having precise source locations when debug info is
available.

Anastasia Stulova b607e0f238 [OpenCL] Eliminate warning when declaring OpenCL builtin functions.
OpenCL builtin functions are usually declared in header files.
Currently clang emits warning for OpenCL builtin functions
which have the same name as standard C library functions.

This commit eliminates such warnings by not adding the C standard
includes following the restriction from OpenCL v1.2 s6.9.f.

Pavel Labath e8baa4498d Fix compiler lookup when specified without path
r259433 introduced a regression, where if a compiler is specified without a path (e.g., CC=clang,
relying on the fact that clang is in $PATH), then the test suite would fail (at the compiler
version detection step) because realpath would interpret this as a path relative to cwd). The fix
is to perform the $PATH expansion (via `which`) before the realpath step.

Chandler Carruth a4499e9f73 [LCG] Build an edge abstraction for the LazyCallGraph and use it to
differentiate between indirect references to functions an direct calls.

This doesn't do a whole lot yet other than change the print out produced
by the analysis, but it lays the groundwork for a very major change I'm
working on next: teaching the call graph to actually be a call graph,
modeling *both* the indirect reference graph and the call graph
simultaneously. More details on that in the next patch though.

The rest of this is essentially a bunch of over-engineering that won't
be interesting until the next patch. But this also isolates essentially
all of the churn necessary to introduce the edge abstraction from the
very important behavior change necessary in order to separately model
the two graphs. So it should make review of the subsequent patch a bit
easier at the cost of making this patch seem poorly motivated. ;]

Philip Reames 44456b8963 [LVI] Introduce an intersect operation on lattice values
LVI has several separate sources of facts - edge local conditions, recursive queries, assumes, and control independent value facts - which all apply to the same value at the same location. The existing implementation was very conservative about exploiting all of these facts at once.

This change introduces an "intersect" function specifically to abstract the action of picking a good set of facts from all of the separate facts given. At the moment, this function is relatively simple (i.e. mostly just reuses the bits which were already there), but even the minor additions reveal the inherent power. For example, JumpThreading is now capable of doing an inductive proof that a particular value is always positive and removing a half range check.

I'm currently only using the new intersect function in one place. If folks are happy with the direction of the work, I plan on making a series of small changes without review to replace mergeIn with intersect at all the appropriate places.
