21a0f26cd1 compiler: do not emit nonstandard !unconditionally* LLVM metadata. 
This metadata was added by an LLVM patch that was removed because
it was unsound.

4b5a78e231 compiler: do not pass files to external tools while they are opened. 
This fixes access violations on Windows that are present both with
input and output files. For some reason, Cygwin-compiled binutils
did not exhibit this problem, but MSYS-compiled binutils do.

Fixes #961.

whitequark
a0a2650fca compiler: do not use invoke for calls to nounwind ffi functions. 
Otherwise, declarations such as:

metadata are no longer compatible since LLVM 4.0.

ca254ec55e compiler: disallow op= on mutable lists only (fix #835). 
This only really applies to lists since those use fat pointers.
`x.y += z` is fine.

e59b301a3b compiler: disallow op= on mutable values (fix #835). 
In general, we can't reallocate a value in earlier stack frames,

ed2b10c5aa compiler: in codegen for delay(), round fp instead of truncating. 
Consider delay(8*us). It results in the following computation...
  >>> 8*1e-06/1e-09
  7999.999999999999
with the result promptly getting truncated to 7999.

7e886ddc89 transforms.inferencer: do not unnecessarily mutate typedtree. 
This caused the hash to change after every iteration of inference,
if the result of any coercion was an integer of indefinite width.

whitequark
4107938fd8 compiler.embedding: use attribute count in fixpoint condition. 
Before this commit, we had a hack where inferencing would run
one more time, in case we can still infer more attributes even
after all the type information is there. This doesn't work
if *that* round of inferencing brings even more code, e.g.
this is easy to trigger with context managers.

3a1f14c16c compiler: fix overly strict constness analysis. 
Before this commit, the following code would fail to compile...
  obj.foo.bar = True
... if foo is marked kernel_invariant in obj, even if bar is not
marked as such in obj.foo.

4305903dde compiler: rein in overzealous cast monomorphization. 
This caused failures on e.g. "int32(var64a >> var64b)", where
the type of the argument is already fully known, but was unified
with the result of the cast anyway.

35f4449ef2 inferencer: significantly improve the op-assignment diagnostic. 
Before this commit, it displayed incorrect output if an error
appeared on 2nd run and beyond, and displayed messages for trying

bfbdba9205 compiler: Emit all-kernel_invariant objects as LLVM constants 
This enables constant propagation optimisations, as verified by

we should support optimisation based on kernel invariants on a more
fine-grained level.
