Luke Drummond 482e890d1f [tablegen] Emit string literals instead of char arrays
This changes the generated (Instr|Asm|Reg|Regclass)Name tables from this
form:
    extern const char HexagonInstrNameData[] = {
      /* 0 */ 'G', '_', 'F', 'L', 'O', 'G', '1', '0', 0,
      /* 9 */ 'E', 'N', 'D', 'L', 'O', 'O', 'P', '0', 0,
      /* 18 */ 'V', '6', '_', 'v', 'd', 'd', '0', 0,
      /* 26 */ 'P', 'S', '_', 'v', 'd', 'd', '0', 0,
      [...]
    };

...to this:

    extern const char HexagonInstrNameData[] = {
      /* 0 */ "G_FLOG10\0"
      /* 9 */ "ENDLOOP0\0"
      /* 18 */ "V6_vdd0\0"
      /* 26 */ "PS_vdd0\0"
      [...]
    };

This should make debugging and exploration a lot easier for mortals,
while providing a significant compile-time reduction for common compilers.

To avoid issues with low implementation limits, this is disabled by
default for visual studio.

To force output one way or the other, pass
`--long-string-literals=<bool>` to `tablegen`

A variation of this patch was originally committed in ce23515f5a and
then reverted in e464b31c due to build failures.

Sergej Jaskiewicz e464b31c15 Revert "[tablegen] Emit string literals instead of char arrays"
This reverts commit ce23515f5a.

That commit broke some builds on Windows:

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Benjamin Kramer 591aac7cdf Remove usages of deprecated std::unary_function and std::binary_function.
These are removed in C++17. We still have some users of
unary_function::argument_type, so just spell that typedef out. No
functionality change intended.

Note that many of the argument types are actually wrong :)

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'

Craig Topper c3c002d0b6 Reduce size of some tables in tablegen register info output.
Primarily done by using SequenceToOffsetTable to reduce the register pressure set tables and then sizing the indices into the tables appropriately. Size a few other table entries based on content as well. Reduces X86RegisterInfo.o by ~9k.

Benjamin Kramer a7c40ef022 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

Chandler Carruth 91d19d8e93 Sort the #include lines for utils/...
I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

Craig Topper f8f0a23ce7 Revert r163878 as it breaks on targets with alternate register names. Such targets do not exist in the main tree so this was not noticed.

Craig Topper 805e39beab Reduce size of register name index tables by using uint16_t for all in tree targets. If more than 16-bits are needed for any out of tree targets, code will detect and use uint32_t instead.

Chris Lattner a3b0f52a72 enhance the intrinsic info stuff to emit encodings that don't fit in 32-bits into a
separate side table, using the handy SequenceToOffsetTable class.  This encodes all
these weird things into another 256 bytes, allowing all intrinsics to be encoded this way.

Jakob Stoklund Olesen 892f48058b Use SequenceToOffsetTable in emitRegisterNameString.
This allows suffix sharing in register names. (AX is a suffix of EAX).

Jakob Stoklund Olesen 066aba5fe9 Reapply 153764 and 153761 with a fix.
Use an explicit comparator instead of the default.

The sets are sorted, but not using the default comparator. Hopefully,
this will unbreak the Linux builders.

Jakob Stoklund Olesen e214c3df40 Compress SimpleValueType lists by sharing.
Many register classes have the same value types. Share the table space.

Jakob Stoklund Olesen a234f2efbd Add a SequenceToOffsetTable to TableGen.
This is similar to the StringToOffsetTable we use to produce string
tables, but it can be used for other sequences than strings, and it
eliminates entries for suffixes.
