Import the builtin type prefix before we import the user expression prefix so that the user expression prefix can use the uint, int, size_t, and other types without having to define them.

The removal is tried by retrying the failed lookup of a correction
candidate with either the MemberContext or SS (CXXScopeSpecifier) or
both set to NULL if they weren't already. If the candidate identifier
is then looked up successfully, make a note in the candidate that the
SourceRange should include any existing nested name specifier even if
the candidate isn't adding a different one (i.e. the candidate has a
NULL NestedNameSpecifier).

Also tweak the diagnostic messages to differentiate between a suggestion
that just replaces the identifer but leaves the existing nested name
specifier intact and one that replaces the entire qualified identifier,
in cases where the suggested replacement is unqualified.

CorrectTypo will now see and consider those corrections that are effectively
shadowed by other declarations in a closer context when resolved via an
unqualified lookup. This involves adding any parent namespaces to the set of
namespaces as fully-qualified name specifiers, and also adding potential
corrections that passed name lookup but were rejected by the given
CorrectionCandidateCallback into the set of failed corrections that should be
tried with the set of namespace specifiers.

Correctly handles ref_addr depending on the Dwarf version. Emit Dwarf with
version from module flag.

TODO: turn on/off features depending on the Dwarf version.
llvm-svn: 185484

Darwin systems currently do not support dwarf version 3 or above. When we are
ready, we can bump the default to gdwarf-4 for Darwin.

For other systems, the default is dwarf version 3, if everything goes smoothly,
we can bump the version to 4.

[PowerPC] PR16512 - Support TLS call sequences in the asm parser

This patch now adds support for recognizing TLS call sequences in
the asm parser.  This needs a new pattern BL8_TLS, which is like
BL8_NOP_TLS except without nop.  That pattern is used for the
asm parser only.

llvm-svn: 185478

[PowerPC] Rework TLS call operand processing

As part of the global-dynamic and local-dynamic TLS sequences, we need
to use a special form of the call instruction:

 bl __tls_get_addr(sym@tlsld)
 bl __tls_get_addr(sym@tlsgd)

which generates two fixups.  The current implementation of this causes
problems with recognizing this form in the asm parser.  To fix this,
this patch reworks operand processing for this special form by using
a single operand to hold both __tls_get_addr and sym@tlsld and defining
a print method to output the above form, and an encoding method to
generate the two fixups.

As a side simplification, the patch replaces the two instruction
patterns BL8_NOP_TLSGD and BL8_NOP_TLSLD by a single BL8_NOP_TLS,
since the patterns already operate in an identical fashion (whether
we have a local-dynamic or global-dynamic symbol is already encoded
in the symbol modifier).

No change in code generation intended.

[PowerPC] Remove VK_PPC_TLSGD and VK_PPC_TLSLD

The PowerPC-specific modifiers VK_PPC_TLSGD and VK_PPC_TLSLD
correspond exactly to the generic modifiers VK_TLSGD and VK_TLSLD.
This causes some confusion with the asm parser, since VK_PPC_TLSGD
is output as @tlsgd, which is then read back in as VK_TLSGD.

To avoid this confusion, this patch removes the PowerPC-specific
modifiers and uses the generic modifiers throughout.  (The only
drawback is that the generic modifiers are printed in upper case
while the usual convention on PowerPC is to use lower-case modifiers.
But this is just a cosmetic issue.)

[PowerPC] Support TLS variables in debug info

This adds an implementation of getDebugThreadLocalSymbol for
(64-bit) PowerPC.  This needs to return a generic MCExpr
since on ppc64, we need to add a bias of 0x8000 to the
value returned by the R_PPC64_DTPREL64 relocation.

llvm-svn: 185461

[DebugInfo] Allow getDebugThreadLocalSymbol to return MCExpr

This allows getDebugThreadLocalSymbol to return a generic MCExpr
instead of just a MCSymbolRefExpr.

This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.

[DebugInfo] Hold generic MCExpr in AddrPool

This changes the AddrPool infrastructure to enable it to hold
generic MCExpr expressions, not just MCSymbolRefExpr.

This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.

[DebugInfo] Introduce DIEExpr variant of DIEValue to hold MCExpr values

This partially reverts r185202 and restores DIELabel to hold plain
MCSymbol references.  Instead, we add a new subclass DIEExpr of
DIEValue that can hold generic MCExpr references.

This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.

implementation and all of the char buffers readily have their
allocated size available, so we can easily use snprintf_l instead of
sprintf_l.

This avoids OpenBSD's linker warnings against using sprintf and
vsprintf.

Unlike Itanium, there is no code to indicate the beginning of a
parameter pack.  I tested this with MSVC 2013, which is the only version
that implements variadic templates so far.

This is needed to compile APInt.cpp for the MS C++ ABI.
