Mehdi Amini b550cb1750 [NFC] Header cleanup
Removed some unused headers, replaced some headers with forward class declarations.

Found using simple scripts like this one:
clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap'

Daniel Sanders b3c2764f89 [mips] Range check simm32 and fold MIPS16's imm32 into simm32.
Summary:
At this point we should be able to enable IAS by default for O32 without

Daniel Sanders 85fd10bd93 [mips] Range check simm16
Summary:
There are too many instructions to exhaustively test so addiu and lwc2 are
used as representative examples.

It should be noted that many memory instructions that should have simm16
range checking do not because it is also necessary to support the macro
of the same name which accepts simm32. The range checks for these occur in
the macro expansion.

Daniel Sanders eab3146156 [mips] Range check simm11 and mem_simm11.
Summary:
ldc2/sdc2 now emit slightly worse diagnostics for MIPS-I. The problem
is that they don't trigger the custom parser because all the candidates
are disabled by feature bits. On all other subtargets, the diagnostics are
accurate but are subject to the usual issues of needing to report multiple
ways to correct the code (e.g. smaller offset, enable a CPU feature) but
only being able to report one error.

Daniel Sanders f8bb23e509 [mips] Range check uimm16 and fix several bugs this revealed.
Summary:
The bugs were:
* teq and similar take 4-bit unsigned immediates on microMIPS.
* teqi and similar have side-effects like teq do.
* shll_s.w and shra_r.w take 5-bit unsigned immediates.
* The various DSP ext* instructions take a 5-bit immediate.
* repl.qh takes an 8-bit unsigned immediate.
* repl.ph takes a 10-bit unsigned immediate.
* rddsp/wrdsp take a 10-bit unsigned immediate.
* teqi and similar take signed 16-bit immediates (10-bit for microMIPS).
* Out-of-range immediate macros for or/xor take a simm32/simm64 depending
  on architecture. I'll fix the simm64 case properly when I reach simm32.

lui is a bit more lenient than GAS and accepts signed immediates in addition
to unsigned. This is because MipsMCExpr can produce signed values when
constant folding and it currently lacks a way of knowing it should fold to
an unsigned value.

Daniel Sanders daa4b6fbd9 [mips][ias] Range check uimm5 operands and fix several bugs this revealed.
Summary:
The bugs were:
* append, prepend, and balign were not tested
* balign takes a uimm2 not a uimm5.
* drotr32 was correctly implemented with a uimm5 but the tests expected
  '52' to be valid.
* li/la were implemented with a uimm5 instead of simm32. simm32 isn't
  completely correct either but I'll fix that when I get to simm32.

A notable omission are some of the shift instructions. Several of these
have been implemented using a single uimm6 instruction (rather than two
uimm5 instructions and a CodeGen-only uimm6 pseudo). These will be updated
in the uimm6 patch.

Akira Hatanaka b11ef0897c Reduce the size of MCRelaxableFragment.
MCRelaxableFragment previously kept a copy of MCSubtargetInfo and
MCInst to enable re-encoding the MCInst later during relaxation. A copy
of MCSubtargetInfo (instead of a reference or pointer) was needed
because the feature bits could be modified by the parser.

This commit replaces the MCSubtargetInfo copy in MCRelaxableFragment
with a constant reference to MCSubtargetInfo. The copies of
MCSubtargetInfo are kept in MCContext, and the target parsers are now
responsible for asking MCContext to provide a copy whenever the feature
bits of MCSubtargetInfo have to be toggled.
 
With this patch, I saw a 4% reduction in peak memory usage when I
compiled verify-uselistorder.lto.bc using llc.

Daniel Sanders 153010c52d Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.
Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).

For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.

This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.

Daniel Sanders a699444094 [mips] Make the MipsAsmParser capable of knowing whether PIC mode is enabled or not.
Summary:
This information is needed to decide whether we do the PIC-only JAL expansions or not. It's also needed for an upcoming patch which implements the .cprestore assembler directive (which can only be used effectively in PIC mode).

By making this information available to the MipsAsmParser, we will know when to insert the instructions mandated by the .cprestore assembler directive and we will be able to give some useful warnings when we encounter a potential misuse of this directive.

Daniel Sanders 03f9c019d2 [mips] Fix li/la differences between IAS and GAS.
Summary:
- Signed 16-bit should have priority over unsigned.
- For la, unsigned 16-bit must use ori+addu rather than directly use ori.
- Correct tests on 32-bit immediates with 64-bit predicates by
  sign-extending the immediate beforehand. For example, isInt<16>(0xffff8000)
  should be true and use addiu.

Also split li/la testing into separate files due to their size.

This prevents us from forgetting to update the STI.FeatureBits,

Toma Tabacu 7bc44dcb0c [mips] [IAS] Fix parsing of memory offset expressions with parenthesis depth >1.
Summary:
In an expression such as "(((a+b)+c)+d)", parseParenExpression() would only parse the "a+b)+c", which would result in an error later on in the parser.
This means that we can only parse one level of inner parentheses.

In order to fix this, I added a new function called parseParenExprOfDepth(), which parses a specified number of trailing parenthesis expressions
(except for the outermost parenthesis), and changed MipsAsmParser to use it in parseMemOffset instead of parseParenExpression().

Toma Tabacu 07c97b3b7e [mips] [IAS] Fix LW with relative label operands.
Summary:
Previously, MCSymbolRefExpr::create() was called with a StringRef of the symbol
name, which it would then search for in the Symbols StringMap (from MCContext).

However, relative labels (which are temporary symbols) are apparently not stored
in the Symbols StringMap, so we end up creating a new {$,.L}tmp symbol
({$,.L}tmp00, {$,.L}tmp10 etc.) each time we create an MCSymbolRefExpr by
passing in the symbol name as a StringRef.

Fortunately, there is a version of MCSymbolRefExpr::create() which takes an
MCSymbol* and we already have an MCSymbol* at that point, so we can just pass
that in instead of the StringRef.

I also removed the local StringRef calls to MCSymbolRefExpr::create() from
expandMemInst(), as those cases can be handled by evaluateRelocExpr() anyway.
