8b1c5e3a26 llvm_ir_generator: add fast-math flags to fcmp. 
This is allowed in 3.8.

ad83b092fa llvm_ir_generator: change !{→unconditionally_}dereferenceable. 
Since LLVM 3.8, !dereferenceable is weaker, so we introduce
!unconditionally_dereferenceable (http://reviews.llvm.org/D18738)
to regain its functionality.

8a908a7656 llvm_ir_generator: do not use 'coldcc' calling convention. 
First, this calling convention doesn't actually exist in OR1K
and trying to use it in Asserts build causes an UNREACHABLE.

Second, I tried to introduce it and it does not appear to produce
any measurable benefit: not only OR1K has a ton of CSRs but also
it is quite hard, if not realistically impossible, to produce
the kind of register pressure that would be relieved by sparing
a few more CSRs for our exception raising function calls, since
temporaries don't have to be preserved before a noreturn call
and spilling over ten registers across an exceptional edge
is not something that the code we care about would do.

Third, it produces measurable drawbacks: it inflates code size
of check:* functions by adding spills. Of course, this could be
alleviated by making __artiq_raise coldcc as well, but what's
the point anyway?

1d8b0d46bc compiler: mark FFI functions as ModRef=Ref using TBAA metadata. 
Fascinatingly, the fact that you can mark call instructions with
!tbaa metadata is completely undocumented. Regardless, it is true:
a !tbaa metadata for an "immutable" type will cause
AliasAnalysis::getModRefBehavior to return OnlyReadsMemory for that
call site.

Don't bother marking loads with TBAA yet since we already place
!load.invariant on them (which is as good as the TBAA "immutable"
flag) and after that we're limited by lack of !nonnull anyway.

Also, add TBAA analysis passes in our pipeline to actually engage it.

81427af506 Remove selective attribute writeback; always synchronize all attributes. 
The reasons are:
  1. Shadow memory manipulation added ~12 instructions to TTLOut.pulse
     (without inlining), and it's already barely fast enough.
  2. More importantly, code such as self.ts[1] did not trigger
     attribute writeback, and there seems to be no easy way to fix
     that.

9ed6b54249 transforms.cfg_simplifier: remove. 
Specifically, the following idiom broke our CFGSimplifier:

b1:
  branch_if %cond, %b2, %b3
b2:
  branch %b3
b3:
  %v = phi [ %b2 => 0, %b3 => 1 ]

This is very annoying to properly handle in general case, and also
this (specifically %b2) is exactly what broke LocalAccessValidator
in the first place. So, remove CFGSimplifier altogether.

Instead, teach LocalAccessValidator how to look through predecessors
in order to get a location.
