Support loads with differently sized types from a single array
We support now code such as:
void multiple_types(char *Short, char *Float, char *Double) {
for (long i = 0; i < 100; i++) {
Short[i] = *(short *)&Short[2 * i];
Float[i] = *(float *)&Float[4 * i];
Double[i] = *(double *)&Double[8 * i];
}
}
To support such code we use as element type of the modeled array the smallest
element type of all original array accesses. Accesses with larger types are
modeled as multiple accesses with the smaller type.
For example the second load access is modeled as:
{ Stmt_bb2[i0] -> MemRef_Float[o0] : 4i0 <= o0 <= 3 + 4i0 }
To support jscop-rewritable memory accesses we need each statement instance to
only be assigned a single memory location, which will be the address at which
we load the value. Currently we obtain this address by taking the lexmin of
the access function. We may consider keeping track of the memory location more
explicitly in the future.

The second issue was in the handling of these symbols when we emit

Summary:
This is a workaround to a problem in the 3.8 release that affects MIPS and

supported.
When TSAN_SUPPORTED_ARCH is not empty, cmake currently attempts to build a
tsan'd libcxx as well as test tsan for the default target regardless of whether
the default target is supported or not. This causes problems on MIPS32 since
tsan is supported for MIPS64 but not MIPS32.
This patch causes cmake to only build the libcxx and run the lit test-suite for
archictures in ${TSAN_SUPPORTED_ARCH}
This re-commit fixes an issue where 'check-tsan' continued to look for the

[tsan] Add a libc++ and lit testsuite for each ${TSAN_SUPPORTED_ARCH}.
Summary:
This is a workaround to a problem in the 3.8 release that affects MIPS and
possibly other targets where the default is not supported but a sibling is
supported.
When TSAN_SUPPORTED_ARCH is not empty, cmake currently attempts to build a
tsan'd libcxx as well as test tsan for the default target regardless of whether
the default target is supported or not. This causes problems on MIPS32 since
tsan is supported for MIPS64 but not MIPS32.
This patch causes cmake to only build the libcxx and run the lit test-suite for
archictures in ${TSAN_SUPPORTED_ARCH}

Fix single stepping over the IT instruction
The ARM instruction emulator had 2 bugs related to the handling of the
IT instruction causing an error in single stepping:
* We haven't initialized the IT mask from the CPSR so if the last
instruction of the IT block is a branch and the condition is false
then the emulator evaluated the branch what resulted in an incorrect
pc for the next instruction.
* The ITSTATE was advanced before the execution of each instruction. As
a result the emulator was using the condition of following instruction
in every case. The ITSTATE should be edvanced after the execution of
an instruction except after an IT instruction.

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.

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.

[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.

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.
