Craig Topper 8d68422121 Use uint16_t to store InstrNameIndices in MCInstrInfo. Add asserts to protect all 16-bit string table offsets. Also make sure the string to offset table string is not larger than 65536 characters since larger string literals aren't portable.

Chandler Carruth d4ba3eb480 Switch this code to use hash_combine_range rather than incremental calls
to hash_combine. One of the interfaces could already do this, and the
other can just use a small buffer. This is a much more efficient way to
use the hash_combine interface, although I don't have any particular
benchmark where this code was hot, so I can't measure much of an impact.
It at least doesn't slow anything down.

Richard Smith 3e4a60a2cd Add -Wc++11-compat warning for string and character literals followed by
identifiers, in cases where those identifiers would be treated as
user-defined literal suffixes in C++11.

Chandler Carruth cee7a12d40 Cache the sized-ness of struct types, once we reach the steady state of
"is sized". This prevents every query to isSized() from recursing over
every sub-type of a struct type. This could get *very* slow for
extremely deep nesting of structs, as in 177.mesa.

This change is a 45% speedup for 'opt -O2' of 177.mesa.linked.bc, and
likely a significant speedup for other cases as well. It even impacts
-O0 cases because so many part of the code try to check whether a type
is sized.

Thanks for the review from Nick Lewycky and Benjamin Kramer on IRC.

lldb crashes under guard malloc

Fix CommandObjectSettingsAppend::ExecuteRawCommandString() so that it does not perform the cmd_args.Shift()
operation after it has got the var_name out of the raw string, since StringRef is manipulating the raw

Argyrios Kyrtzidis 4a280ff48f [PCH] Mark a PCH file with a flag to indicate if the serialized AST had
compiler errors or not.

-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.

[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.

The general idea is that we want libclang to stay functional even if a PCH had a compiler error.

Andrew Trick 9179e8a4a3 More git-svn compatible version string, by request.
If you're using git-svn, the clang and llvm repository will typically
map to a different revision.

Before we had:
clang version 3.1 (trunk 152167 trunk 152162)

After this change:
clang version 3.1 (trunk 152167) (llvm/trunk 152162)

So it's self-descriptive with an extra parens group. Which is more
compatible with version string parsers is probably debatable, but this
style was requested.

Michael Han 4a04517329 Refactor Clang sema attribute handling.
This submission improves Clang sema handling by using Clang tablegen
to generate common boilerplate code. As a start, it implements AttributeList
enumerator generation and case statements for AttributeList::getKind.

A new field "SemaHandler" is introduced in Attr.td and by default set to 1
as most of attributes in Attr.td have semantic checking in Sema. For a small
number of attributes that don't appear in Sema, the value is set to 0.

Also there are a small number of attributes that only appear in Sema but not
in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.

Dylan Noblesmith bb8c7dabed AST: fix build since r152060
The declarations of the operators no longer matched.
The definitions in ASTContext.h had 'throw()' removed,
but it was still present in Attr.h.

Somehow the buildbots missed this. clang merely warns about
a missing 'throw()' specification and suggested a Fix-It adding
it back, but gcc 4.5 is not so forgiving and gives an error.
