Justin Lebar 38746d9718 [NVPTX] Let there be One True Way to set NVVMReflect params.
Summary:
Previously there were three ways to inform the NVVMReflect pass whether
you wanted to flush denormals to zero:

  * An LLVM command-line option
  * Parameters to the NVVMReflect constructor
  * Metadata on the module itself.

This change removes the first two, leaving only the third.

The motivation for this change, aside from simplifying things, is that
we want LLVM to be aware of whether it's operating in FTZ mode, so other
passes can use this information.  Ideally we'd have a target-generic
piece of metadata on the module.  This change moves us in that
direction.

Renato Golin 124f2593fc [docs] Fixing Sphinx warnings to unclog the buildbot
Lots of blocks had "llvm" or "nasm" syntax types but either weren't following
the syntax, or the syntax has changed (and sphinx hasn't keep up) or the type
doesn't even exist (nasm?).

Other documents had :options: what were invalid. I only removed those that had
warnings, and left the ones that didn't, in order to follow the principle of
least surprise.

This is like this for ages, but the buildbot is now failing on errors. It may
take a while to upgrade the buildbot's sphinx, if that's even possible, but
that shouldn't stop us from getting docs updates (which seem down for quite
a while).

Also, we're not losing any syntax highlight, since when it doesn't parse, it
doesn't colour. Ie. those blocks are not being highlighted anyway.

I'm trying to get all docs in one go, so that it's easy to revert later if we
do fix, or at least easy to know what's to fix.

Justin Lebar e3804cc932 [NVPTX] Make NVVMReflect a function pass.
Summary:
Currently it's a module pass.  Make it a function pass so that we can
move it to PassManagerBuilder's EP_EarlyAsPossible extension point,
which only accepts function passes.
