ccc: Allow downstream tools to be aware of final output name.
 - This is a hack to allow the Darwin linker to get -final_output when
   doing universal builds; the mechanism should be generalized.

 - Handle multiple redundant -arch arguments correctly.

 - Forward -arch_multiple and -final_output to gcc when necessary.

 - Simplified implementation of derived gcc tools.

Convert more exprs to use ASTContext's Allocator.

When using a BumpPtrAllocator, this reduces malloc overhead from 2.2->1.9% (for Cocoa.h).

At this point, malloc() has dropped the fourth most expensive routine (behind Preprocessor::HandleIdentifier()).

Optimize Declarator to avoid malloc/free traffic for the argument list of a
function DeclaratorChunk in common cases.  This uses a fixed array in
Declarator when it is small enough for the first function declarator chunk
in a declarator.

This eliminates all malloc/free traffic from DeclaratorChunk::getFunction
when running on Cocoa.h except for five functions: signal/bsd_signal/sigset,
which have multiple Function DeclChunk's, and
CFUUIDCreateWithBytes/CFUUIDGetConstantUUIDWithBytes, which take more than
16 arguments.

This patch was pair programmed with Steve.

Remove ScopedDecl, collapsing all of its functionality into Decl, so
that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

PTH: Emitted tokens now consist of 12 bytes that are loaded used 3 32-bit loads.  This reduces user time but increases system time because of the slightly larger PTH file.  Although there is no performance win on Cocoa.h and -Eonly, overall this seems like a good step.

On i386 and x86-64, just do unaligned loads
instead of assembling from bytes.  This speeds up -Eonly PTH reading
of cocoa.h by about 2ms, which is 4.2%.

Handle the 'X' constraint. Fixes <rdar://problem/6504897>.

switch PTHLexer to use Read32 and friends instead of lots of inlined
copies.  I verified that this causes no performance change in PTH.

CG support for inline asm constraints with symbolic names. Fixes PR3345

A couple more vector component access fixes.

switch PTH lexer from using "const char*"s to "const unsigned char*"s
internally.  This is just a cleanup that reduces the need to cast to
unsigned char before assembling a larger integer.

Change TargetInfo::validateInputConstraint to take begin/end name iterators instead of the number of outputs. No functionality change.

Patch to re-implement ivar-list meta-data generation to fix
cases of unnamed ivar bitfields.

Rename SourceLocation::getFileID to getChunkID, because it returns
the chunk ID not the file ID.  This exposes problems in
TextDiagnosticPrinter where it should have been using the canonical
file ID but wasn't.  Fix these along the way.

simplify some lookups.

Change the Lexer ctor used to lex _Pragma directives into a static factory
method.  This lets us clean up the interface and make it more obvious that
this method is *really really* _Pragma specific.

Note that _Pragma handling uglifies the Lexer in the critical path.  It would
be very interesting to consider making _Pragma remapping be a new special
lexer class of its own.

Change the Lexer ctor used in the non _Pragma case to take a FileID instead
of a SourceLocation.  This should speed it up and definitely simplifies it.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62422 91177308-0d34-0410-b5e6-96231b3b80d8

in Preprocessor::AdvanceToTokenCharacter, don't actually bother
creating a whole lexer when we just want one static method.

make the verbose raw-lexer ctor fully explicit instead of having
embedded magic.

add a simplified lexer ctor that sets up the lexer to raw-lex an
entire file.
