use in KEXTs. However, users/Xcode still need to tweak the linker flags to do 
the right thing, and end up using -Xlinker, for example.  Instead, have the 
driver "do the right thing" when linking when -fapple-kext is present on the 
command line, and we should have Xcode use -fapple-kext instead of setting other
flags like -Xlinker -kext or -nodefaultlibs.

This can happen in cases where TableGen generated asm matcher cannot check
whether a register operand is in the right register class. e.g. mem operands.

self.expect("expression -- '(anonymous namespace)::i'", VARIABLES_DISPLAYED_CORRECTLY,
            substrs = [" = 3"])

to get rid of the '(anonymous namespace)', which is not c++ syntax, thingy fed to the expression parser.
According to rdar://problem/8668674.  It is still marked expectedFailure since the bug has not been fixed.

llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
    pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored.  The others remain unchanged.

  - Added LazyVector::erase() to support this use case.
  - Factored out the LazyDecl-of-Decls to RecordData translation in
  the ASTWriter. There is still a pile of code duplication here to
  eliminate.

Add a utility function to the Lexer, which makes it easier to find a token after the given location. (It is a generalized version of trans::findLocationAfterSemi from ArcMigrate, which will be changed to use the Lexer utility).

Encode the width operand as it encodes in the instruction, which simplifies
the disassembler and the encoder, by using the imm1_32 operand def. Add a
diagnostic for the context-sensitive constraint that the width must be in
the range [1,32-lsb].

contents are lazily loaded on demand from an external source (e.g., an
ExternalASTSource or ExternalSemaSource). The "loaded" entities are
kept separate from the "local" entities, so that the two can grow
independently.

Switch Sema::TentativeDefinitions from a normal vector that is eagerly
populated by the ASTReader into one of these LazyVectors, making the
ASTReader a bit more like me (i.e., lazy).
