cf03606efc [TableGen] Cleanup Record comments. NFC. 
LLVM doesn't use exceptions anymore.
Also remove the implementation comments. Some of them diverged.

69ada669bc AArch64: TableGenerate system instruction operands. 
The way the named arguments for various system instructions are handled at the
moment has a few problems:

  - Large-scale duplication between AArch64BaseInfo.h and AArch64BaseInfo.cpp
  - That weird Mapping class that I have no idea what I was on when I thought
    it was a good idea.
  - Searches are performed linearly through the entire list.
  - We print absolutely all registers in upper-case, even though some are
    canonically mixed case (SPSel for example).
  - The ARM ARM specifies sysregs in terms of 5 fields, but those are relegated
    to comments in our implementation, with a slightly opaque hex value
    indicating the canonical encoding LLVM will use.

This adds a new TableGen backend to produce efficiently searchable tables, and
switches AArch64 over to using that infrastructure.

edff0683c8 TableGen: promote "code" type from syntactic sugar. 
It's being immediately converted to a "string", but being able to tell what
type the field was originally can be useful in backends.

5f0f4b69f4 [TableGen] Use a SmallVector for Record::Values to avoid debug iterators 
Debug iterators are valuable so we don't want to turn them off
completely. However, llvm-tblgen is critical to build speed, so we can
skip them here.

Regenerating X86GenSubtargetInfo.inc in a clang-cl self-host debug build
now takes 39s instead of 1m29s.

6ebd4e68e8 Minor performance tweaks to llvm-tblgen (and a few that might be a good idea) 
Summary:
This patch adds a reserve call to an expensive function
(`llvm::LoadIntrinsics`), and may fix a few other low hanging
performance fruit (I've put them in comments for now, so we can
discuss).

**Motivation:**

As I'm sure other developers do, when I build LLVM, I build the entire
project with the same config (`Debug`, `MinSizeRel`, `Release`, or
`RelWithDebInfo`). However, the `Debug` config also builds llvm-tblgen
in `Debug` mode. Later build steps that run llvm-tblgen then can
actually be the slowest steps in the entire build. Nobody likes slow
builds.

fa21741f38 [llvm-tblgen] Avoid StringMatcher for GCC and MS builtin names 
This brings the compile time of Function.cpp from ~40s down to ~4s for
me locally. It also shaves off about 400KB of object file size in a
release+asserts build.

I also realized that the AMDGPU backend does not have any GCC builtin
names to match, so the extra lookup was a no-op. I removed it to silence
a zero-length string table array warning. There should be no functional
change here.

This change really ends the story of PR11951.

be43b88fae [TableGen] Merge RecTy::typeIsConvertibleTo and RecTy::baseClassOf. NFC 
typeIsConvertibleTo was just calling baseClassOf(this) on the argument passed to it, but there weren't different signatures for baseClassOf so passing 'this' didn't really do anything interesting. typeIsConvertibleTo could have just been a non-virtual method in RecTy. But since that would be kind of a silly method, I instead re-distributed the logic from baseClassOf into typeIsConvertibleTo.
