I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

the '~' operator as part of MCExpr::parseExpression.
As a result:
* expressions and immediates no longer have different parsing rules. The
difference is now solely down to whether evaluateAsAbsolute() succeeds.
* %hi(%neg(%gp_rel(x))) are no longer parsed as a single operator and
decomposed into the three MipsMCExpr nodes. They are parsed directly as
three MipsMCExpr nodes.
* parseMemOperand no longer needs to eat all the surrounding parenthesis
to get at the outermost operator to make this work
* %hi(%neg(%gp_rel(x))) and %lo(%neg(%gp_rel(x))) are no longer the only
3-in-1 relocs that parse for N64. They're still the only combinations that
are permitted in relocatable expressions though. Fixing that should be a
later patch.
* We no longer need to list all the tokens that can occur as the first token of
an expression or immediate.

llvm-svn: 277988
Summary:
This is one possible solution to the problem of ignoring constraints that Simon
raised in D21473 but it's a bit of a hack.
The integrated assembler currently ignores violations of the tied register
constraints when the operands involved in a tie are both present in the AsmText.
For example, 'dati $rs, $rt, $imm' with the '$rs = $rt' will silently replace
$rt with $rs. So 'dati $2, $3, 1' is processed as if the user provided
'dati $2, $2, 1' without any diagnostic being emitted.
This is difficult to solve properly because there are multiple parts of the
matcher that are silently forcing these constraints to be met. Tied operands are
rendered to instructions by cloning previously rendered operands but this is
unnecessary because the matcher was already instructed to render the operand it
would have cloned. This is also unnecessary because earlier code has already
replaced the MCParsedOperand with the one it was tied to (so the parsed input
is matched as if it were 'dati <RegIdx 2>, <RegIdx 2>, <Imm 1>'). As a result,
it looks like fixing this properly amounts to a rewrite of the tied operand
handling which affects all targets.
This patch however, merely inserts a checking hook just before the
substitution of MCParsedOperands and the Mips target overrides it. It's not
possible to accurately check the registers are the same this early (because
numeric registers haven't been bound to a register class yet) so it cheats a
bit and checks that the tokens that produced the operand are lexically
identical. This works because tied registers need to have the same register
class but it does have a flaw. It will reject 'dati $4, $a0, 1' for violating
the constraint even though $a0 ends up as the same register as $4.

Summary:
This is much closer to the way MIPS relocation expressions work
(%hi(foo + 2) rather than %hi(foo) + 2) and removes the need for the
various bodges in MipsAsmParser::evaluateRelocExpr().
Removing those bodges ensures that the constant stored in MCValue is the
full 32 or 64-bit (depending on ABI) offset from the symbol. This will be used
to correct the %hi/%lo matching needed to sort the relocation table correctly.
As part of this:
* Gave MCExpr::print() the ability to omit parenthesis when emitting a
symbol reference inside a MipsMCExpr operator like %hi(X). Without this
we print things like %lo(($L1)).
* %hi(%neg(%gprel(X))) is now three MipsMCExpr's instead of one. Most of
the related special cases have been removed or moved to MipsMCExpr. We
can remove the rest as we gain support for the less common relocations
when they are not part of this specific combination.
* Renamed MipsMCExpr::VariantKind and the enum prefix ('VK_') to avoid confusion
with MCSymbolRefExpr::VariantKind and its prefix (also 'VK_').
* fixup_Mips_GOT_Local and fixup_Mips_GOT_Global were found to be identical
and merged into fixup_Mips_GOT.
* MO_GOT16 and MO_GOT turned out to be identical and have been merged into
MO_GOT.
