"bool" should be a context-sensitive keyword in Altivec mode.
PR16456 reported that Clang implements a hybrid between AltiVec's
"Keyword and Predefine Method" and its "Context Sensitive Keyword
Method," where "bool" is always a keyword, but "vector" and "pixel"
are context-sensitive keywords. This isn't permitted by the AltiVec
spec. For consistency with gcc, this patch implements the Context
Sensitive Keyword Method for bool, and stops treating true and false
as keywords in Altivec mode.
The patch removes KEYALTIVEC as a trigger for defining these keywords
in include/clang/Basic/TokenKinds.def, and adds logic for "vector
bool" that mirrors the existing logic for "vector pixel." The test
case is taken from the bug report.

[PowerPC] Use mtocrf when available
Just as with mfocrf, it is also preferable to use mtocrf instead of
mtcrf when only a single CR register is to be written.
Current code however always emits mtcrf. This probably does not matter
when using an external assembler, since the GNU assembler will in fact
automatically replace mtcrf with mtocrf when possible. It does create
inefficient code with the integrated assembler, however.
To fix this, this patch adds MTOCRF/MTOCRF8 instruction patterns and
uses those instead of MTCRF/MTCRF8 everything. Just as done in the
MFOCRF patch committed as 185556, these patterns will be converted
back to MTCRF if MTOCRF is not available on the machine.

the full range of mask operands for the benefit of the asm parser.

[PowerPC] Always use mfocrf if available
When accessing just a single CR register, it is always preferable to
use mfocrf instead of mfcr, if the former is available on the CPU.
Current code makes that distinction in many, but not all places
where a single CR register value is retrieved. One missing
location is PPCRegisterInfo::lowerCRSpilling.
To fix this and make this simpler in the future, this patch changes
the bulk of the back-end to always assume mfocrf is available and
simply generate it when needed.
On machines that actually do not support mfocrf, the instruction
is replaced by mfcr at the very end, in EmitInstruction.
This has the additional benefit that we no longer need the
MFCRpseud hack, since before EmitInstruction we always have
a MFOCRF instruction pattern, which already models data flow
as required.
The patch also adds the MFOCRF8 version of the instruction,
which was missing so far.

Added support in FunctionAttrs for adding relevant function/argument attributes for the posix call gettimeofday.
This implies annotating it as nounwind and its arguments as nocapture. To be
conservative, we do not annotate the arguments with noalias since some platforms

Added posix function gettimeofday to LibFunc::Func for all platforms but Windows.
*NOTE* In a recent version of posix, they added the restrict keyword to the
arguments for this function. From some spelunking it seems that on some
platforms, the call has restrict on its arguments and others it does not. Thus I
left off the restrict keyword from the function prototype in the comment.

Allow typo correction to try removing nested name specifiers.
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.

Look for corrections in enclosing namespaces that require a global NestedNameSpecifier.
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.

[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.

[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.)
