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.

Rafael Espindola fc06055173 Revert 153764 and 153761. They broke a --enable-optimized --enable-assertions

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.
