method because getContents().size() already covers it. So computeFragmentSize
can use the generic MCEncodedFragment interface when querying both Data and
Relaxable fragments for contents sizes.

Python OS plug-ins now fetch thread registers lazily.
Also changed SBCommandInterpreter::HandleCommand() to not take the API lock. The logic here is that from the command line you can execute a command that might result in another thread (like the private process thread) to execute python or run any code that can re-enter the public API. When this happens, a deadlock immediately occurs for things like "process launch" and "process attach".

-Wint-to-pointer-cast, added to match GCC's warning by the same name, doesn't
need to be in any other groups (as it isn't in any groups in GCC either).

With the new setting, we are not going to inline any functions that are
more than 50 basic blocks. (The analyzer is 20% faster on several
especially bad benchmarks with the new default.)

In the source
static void f();
static void f();
template<typename T>
static void g() {
f();
}
static void f() {
}
void h() {
g<int>();
}
the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.
With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.

This avoids FileCheck failing over different comment characters in
assembly (notably powerpc64 on Linux vs Darwin) and should fix David's
build-bot.

value in the 64 bit .eh_frame section.
It doesn't however allow exception handling to work
yet since it depends on the correct relocation model
being set in the ELF header flags.

The current Intel Atom microarchitecture has a feature whereby
when a function returns early then it is slightly faster to execute
a sequence of NOP instructions to wait until the return address is ready,
as opposed to simply stalling on the ret instruction until
the return address is ready.
When compiling for X86 Atom only, this patch will run a pass,
called "X86PadShortFunction" which will add NOP instructions where less
than four cycles elapse between function entry and return.
It includes tests.
This patch has been updated to address Nadav's review comments
- Optimize only at >= O1 and don't do optimization if -Os is set
- Stores MachineBasicBlock* instead of BBNum
- Uses DenseMap instead of std::map
- Fixes placement of braces

before doing the comparison.
This is because we can't set "FirstInDeclGroup" consistently; for example, when visiting a DeclStmt we will set
it but we don't set it on the result of clang_getCursorDefinition for a reference of the same declaration.

In Clang/LLVM this seems to be the more common formatting for ##s. There
might still be case that we miss, but we'll fix those as we go along.
Before:
#define A(X)
void function ## X();
After:
#define A(X)
void function##X();

- adds '-h' as an alias for '-help'.
- adds an optional <file> argument
- adds an option -i to in-place edit the given file
- adds a help text to explain what the tool does

This is a first step towards supporting more complex structures such
as #ifs inside unwrapped lines. This patch mostly converts the array-based
UnwrappedLine into a linked-list-based UnwrappedLine. Future changes will
allow multiple children for each Token turning the UnwrappedLine into a
tree.
No functional changes intended.

- Turned off -count-only tests as they aren't supported in cpp11-migrate
yet.
- Updated tests to use new binary name and options to access
loop-convert transform.
- Fixed header guards to not use restricted names.
