15af41a330 Updating MIR Language Reference to include new syntax for symbols and physregs.
External symbols now get the sigil '&' while physical registers get the sigil
'$' for their prefix.

cb61a9aa52 [MachineOperand][MIR] Add isRenamable to MachineOperand.
Summary:
Add isRenamable() predicate to MachineOperand.  This predicate can be
used by machine passes after register allocation to determine whether it
is safe to rename a given register operand.  Register operands that
aren't marked as renamable may be required to be assigned their current
register to satisfy constraints that are not captured by the machine
IR (e.g. ABI or ISA constraints).

46d58287e3 MIParser/MIRPrinter: Compute block successors if not explicitely specified
- MIParser: If the successor list is not specified successors will be
  added based on basic block operands in the block and possible
  fallthrough.

- MIRPrinter: Adds a new `simplify-mir` option, with that option set:
  Skip printing of block successor lists in cases where the
  parser is guaranteed to reconstruct it. This means we still print the
  list if some successor cannot be determined (happens for example for
  jump tables), if the successor order changes or branch probabilities
  being unequal.

d15fd4fdd6 MIRLangRef: Simplify/update documentation
- Refer to options by `-option` instead of `option`
- Use `-mtriple=` instead of `-march` in the example (-march will still
  target the default operating system which is usually not what you want
  in a test)
- Rephrase sentence because output does not go to stdout by default (you
  need -o - for that as should be expected).

dfb328c437 [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.
