There were several issues with the previous implementation.
1) There were no tests.
2) We didn't support creating PDBSymbolTypePointer records for
builtin types since those aren't described by LF_POINTER
records.
3) We didn't support a wide enough variety of builtin types even
ignoring pointers.
This patch fixes all of these issues. In order to add tests,
it's helpful to be able to ignore the symbol index id hierarchy
because it makes the golden output from the DIA version not match
our output, so I've extended the dumper to disable dumping of id
fields.

This allows the hard-coded shouldForceImmediate logic to be removed because
the generated MatchOperandParserImpl makes use of the current context (i.e.
the current mnemonic) to determine parsing behaviour, and so won't first try
to parse a register before parsing a symbol name.
No functional change is intended. gas accepts immediate arguments for call,
tail and lla. This patch doesn't address this discrepancy.

addi a0, a0, foo and lw a0, foo(a0) and similar are now rejected. An explicit
%lo and %pcrel_lo modifier is required. This matches gas behaviour.

Reject bare symbols and accept only %pcrel_hi(sym) for auipc and %hi(sym) for
lui. Also test valid operand modifiers in rv32i-valid.s.
Note this is slightly stricter than gas, which will accept either %pcrel_hi or
%hi for both lui and auipc.

This patch adds two new boolean fields:
- Field `ReadState::IndependentFromDef`.
- Field `WriteState::WritesZero`.
Field `IndependentFromDef` is set for ReadState objects associated with
dependency-breaking instructions. It is used by the simulator when updating data
dependencies between registers.
Field `WritesZero` is set by WriteState objects associated with dependency
breaking zero-idiom instructions. It helps the PRF identify which writes don't
consume any physical registers.

Summary:

Both ANDIo and ANDISo (and the 64-bit versions) are record-form instructions.
When optimizing compares, we handle the former in order to eliminate the compare
instruction but not the latter. This patch just adds the latter to the set of
instructions we optimize.
The reason these instructions need to be handled separately is that they are not
part of the RecFormRel map (since they don't have a non-record-form). The
missing "and-immediate-shifted" is just an oversight in the initial
implementation.

Summary:
FileIndex now provides explicit interfaces for preamble and main file updates.
This avoids growing parameter list when preamble and main symbols diverge
further (e.g. D52078). This also gets rid of the hack in `indexAST` that
inferred main file index based on `TopLevelDecls`.
Also separate `indexMainDecls` from `indexAST`.

Summary:
We can use cl::ResetCommandLineParser() to support different types of
command-lines, as long as we're careful about option lifetimes.
(I tried using subcommands, but the error messages were bad)
I found a mostly-reasonable pattern to isolate the fiddly parts.
Added -scope and -limit flags to the `find` command to demonstrate.
(Note that scope support seems to be broken in dex?)
Fixed symbol lookup to parse symbol IDs.
Caveats:
- with command help (e.g. `find -help`), you also get some spam
about required arguments. This is a bug in llvm::cl, which prints
these to errs() rather than the designated stream.

This tries to make use of evaluateAsRelocatable in AArch64AsmParser::classifySymbolRef
to parse more complex expressions as relocatable operands. It is hopefully better than
the existing code which only handles Symbol +- Constant.
This allows us to parse more complex adr/adrp, mov, ldr/str and add operands. It also
loosens the requirements on parsing addends in ld/st and mov's and adds a number of
tests.

Summary:
The dir component ("somedir" in #include <somedir/fo...>) is considered fixed.
We append "foo" to each directory on the include path, and then list its files.
Completions are of the forms:
#include <somedir/fo^
foo.h>
fox/
The filter is set to the filename part ("fo"), so fuzzy matching can be
applied to the filename only.
No fancy scoring/priorities are set, and no information is added to
CodeCompleteResult to make smart scoring possible. Could be in future.
