Simon Cook 562bc307c0 [Driver] Improve help message for -ffixed-xX flags
This improves the message by adding the missing 'x' prefix in register
names, such that the messages say for example 'Reserve the x10 register',
instead of 'Reserve the 10 register'.

Florian Hahn 1a02aaeaa4 [SCCP] Use SimplifyBinOp for non-integer constant/expressions & overdef.
For non-integer constants/expressions and overdefined, I think we can
just use SimplifyBinOp to do common folds. By just passing a context
with the DL, SimplifyBinOp should not try to get additional information
from looking at definitions.

For overdefined values, it should be enough to just pass the original
operand.

Note: The comment before the `if (isconstant(V1State)...` was wrong
originally: isConstant() also matches integer ranges with a single
element. It is correct now.

David Blaikie e0fd87cc64 llvm-dwarfdump: Return non-zero on error
Makes it easier to test "this doesn't produce an error" (& indeed makes
that the implied default so we don't accidentally write tests that have
silent/sneaky errors as well as the positive behavior we're testing for)

Though the support for applying relocations is patchy enough that a
bunch of tests treat lack of relocation application as more of a warning
than an error - so rather than me trying to figure out how to add
support for a bunch of relocation types, let's degrade that to a warning
to match the usage (& indeed, it's sort of more of a tool warning anyway
- it's not that the DWARF is wrong, just that the tool can't fully cope
with it - and it's not like the tool won't dump the DWARF, it just won't
follow/render certain relocations - I guess in the most general case it
might try to render an unrelocated value & instead render something
bogus... but mostly seems to be about interesting relocations used in
eh_frame (& honestly it might be nice if we were lazier about doing this
relocation resolution anyway - if you're not dumping eh_frame, should we
really be erroring about the relocations in it?))

Johannes Doerfert 17d8334223 [OpenMP] Allow <math.h> to go first in C++-mode in target regions
If we are in C++ mode and include <math.h> (not <cmath>) first, we still
need to make sure <cmath> is read first. The problem otherwise is that
we haven't seen the declarations of the math.h functions when the system
math.h includes our cmath overlay. However, our cmath overlay, or better
the underlying overlay, e.g. CUDA, uses the math.h functions. Since we
haven't declared them yet we get errors. CUDA avoids this by eagerly
declaring all math functions (in the __device__ space) but we cannot do
this. Instead we break the dependence by forcing cmath to go first.

Heejin Ahn b647de9925 [WebAssembly] Use dummy debug info in Emscripten SjLj
Summary:
D74269 added debug info to newly created instructions, including calls
to `malloc` and `free`, by taking debug info from existing instructions
around, whose debug info may or may not be empty.

But there are cases debug info is required by the IR verifier: when both
the caller and the callee functions have DISubprograms, meaning we
already have declarations to `malloc` or `free` with a DISubprogram
attached, newly created calls to `malloc` and `free` should have
non-empty debug info. This patch creates a non-empty dummy debug info in
this case to those calls to make the IR verifier pass.
