clang-tidy: 'size' call that could be replaced with 'empty' on STL containers
We are porting some of the checkers at a company we developed to the Clang Tidy
infrastructure. We would like to open source the checkers that may be useful
for the community as well. This patch is the first checker that is being ported
to Clang Tidy. We also added fix-it hints, and applied them to LLVM:
http://reviews.llvm.org/D6924
The code compiled and the unit tests are passed after the fixits was applied.
The documentation of the checker:
/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a
/// constant-time function, and it is generally more efficient and also shows
/// clearer intent to use empty. Furthermore some containers may implement the
/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.
It also uses some custom ASTMatchers. In case you find them useful I can submit
them as separate patches to clang. I will apply your suggestions to this patch.

Modified LLDB to be able to lookup global variables by address.
This is done by adding a "Variable *" to SymbolContext and allowing SymbolFile::ResolveSymbolContext() so if an address is resolved into a symbol context, we can include the global or static variable for that address.
This means you can now find global variables that are merged globals when doing a "image lookup --verbose --address 0x1230000". Previously we would resolve a symbol and show "_MergedGlobals123 + 1234". But now we can show the global variable name.
The eSymbolContextEverything purposely does not include the new eSymbolContextVariable in its lookup since stack frame code does many lookups and we don't want it triggering the global variable lookups.

[PM] Move TargetLibraryInfo into the Analysis library.
While the term "Target" is in the name, it doesn't really have to do
with the LLVM Target library -- this isn't an abstraction which LLVM
targets generally need to implement or extend. It has much more to do
with modeling the various runtime libraries on different OSes and with
different runtime environments. The "target" in this sense is the more
general sense of a target of cross compilation.
This is in preparation for porting this analysis to the new pass
manager.
No functionality changed, and updates inbound for Clang and Polly.

Fix PR22222
The bug was introduced in r225282. r225282 assumed that sub X, Y is

optimization ignore sub instructions.

Make sure that when a breakpoint is hit but its condition is not met,
the hit count is not updated.
Also, keep the hit count for the breakpoint in the breakpoint. We were
using just the sum of the location's hit counts, but that was wrong since if a shared library is
unloaded, and the location goes away, the breakpoint hit count should not suddenly drop
by the number of hits there were on that location.

[RegisterCoalescer] Remove copies to reserved registers
This allows the RegisterCoalescer to join "non-flipped" range pairs with a
physical destination register -- which allows the RegisterCoalescer to remove
copies like this:
<vreg> = something (maybe a load, for example)
... (things that don't use PHYSREG)
PHYSREG = COPY <vreg>
(with all of the restrictions normally applied by the RegisterCoalescer: having
compatible register classes, etc. )
Previously, the RegisterCoalescer handled only the opposite case (copying
*from* a physical register). I don't handle the problem fully here, but try to
get the common case where there is only one use of <vreg> (the COPY).
An upcoming commit to the PowerPC backend will make this pattern much more
common on PPC64/ELF systems.

Three related changes to help:
The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore. Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required. To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them. This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning.
The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines. The new algorithm correctly breaks on the FIRST newline or LAST space/tab before the target column count rather than treating all whitespace interchangeably.
Command interpreters now have the ability to specify help prologue text and a command prefix string. Neither are used in the current LLDB sources but are required to support REPL-like extensions where LLDB commands must be prefixed and additional help text is required to explain how to access traditional debugging commands.
