Don't depend on LiveIntervals::hasInterval() to determine if a physreg
is reserved and constant.

We don't handle exceptions yet, so we treat them as sinks. ExprEngine
hardcodes messages that are known to raise Objective-C exceptions like -raise,
but it was only checking for +raise:format: and +raise:format:arguments: on
NSException itself, not subclasses.

This should produce the same results as using physreg liveness directly.

properly if there is a join point in the control flow graph that involves
a trylock.  Also changes the source locations of some warnings to be
more consistent.

With regunit liveness permanently enabled, this function would always
return true.

Also remove now obsolete code for checking physreg interference.

This fixes PR5997.

These transforms were disabled because codegen couldn't deal with other
uses of trunc(x). This is now handled by the peephole pass.

This causes no regressions on x86-64.

Original message:
Performance optimizations:
- SwitchInst: case values stored separately from Operands List. It allows to make faster access to individual case value numbers or ranges.
- Optimized IntItem, added APInt value caching.
- Optimized IntegersSubsetGeneric: added optimizations for cases when subset is single number or when subset consists from single numbers only.

Allow divsi3 to take advantage of a hardware unsigned divide when it is available, by replacing an explicit call to udivsi3 with the divide operator.  Patch by Sébastien Bourdeauducq.

On my machine these optimizations gave about 4-6% of compile-time improvement.

* Primarily fixed \param commands with names not matching any actual
  parameters of the documented functions.  In many cases this consists
  just of fixing up the parameter name in the \param to match the code,
  in some it means deleting obsolete documentation and occasionally it
  means documenting the parameter that has replaced the older one that
  was documented, which sometimes means some simple reverse-engineering
  of the docs from the implementation;
* Fixed \param ParamName [out] to the correct format with [out] before
  the parameter name;
* Fixed some \brief summaries.

* Added \file documentation for PPCallbacks.h;
* Added/formated \brief summaries;
* Deleted documentation for parameters that no longer exist;
* Used \param more systematically for documentation of parameters;
* Escaped # characters in Doxygen comments.

llvm-svn: 158978

* Add \file documentation;
* Add \verbatim...\endverbatim markup as needed;
* Add \brief summaries;
* Escaped "::" in Doxygen comments when preceded by space, to avoid a
  Doxygen warning where Doxygen takes this as an explicit link request;
* Add \code...\endcode markup to code examples;
* Fix a grammatical glitch in "is this declarator is a".
