If a null call target is provided, don't emit a dummy call. This
allows the runtime to reserve as little nop space as it needs without
the requirement of emitting a call.

This allows to only link in the needed targets, reducing binary
size and more importantly link time.

Note that this is an incomplete implementation: currently,
LLVM does not have the plumbing which would allow to conditionally
link in AsmPrinter, AsmParser and Disassembler for the targets
which support them. This should be improved in the future.

There is nothing special about quotes and newlines from the object
file point of view, only the assembler has to worry about expanding
the \n and \".

This patch then removes the special handling from the Mangler.

YAML files tend to be very large compared to binary formats because of ASCII
format inefficiency. And the YAML reader consumes an excessively large amount
of memory when parsing a large file. It's very slow too.

For example, I observed that 6MB executable became 120MB YAML file, and the
YAML reader consumed more than 1.5GB memory to load it. The YAML reader even
caused OOM error on 32 bit, causing the entire process to fail.

This patch sets the limit on the YAML file size the linker will try to load in
the RoundTripYAML test as a safeguard.

LDC, the LLVM-based D compiler, is already using LLVM 3.4.

Per feedback from Jordan Rose I realized this wasn't the right way to go.

Also refine test case to capture the intention of this suppression.  Essentially
some developers use __bridge_transfer as if it were a safe CFRelease.

This is useful for debugging issues in the BlockFrequency implementation since
one can easily visualize where probability mass and other errors occur in the
propagation.

bit fields of zero size. Warnings are generated in C++ mode and if
only such type is defined inside extern "C" block.

Adding a test case to make sure that the threshold used in the memory
dependence analysis is respected. The test case also checks that debug
intrinsics are not counted towards this threshold.

This dependency needs to be cleaned up at some point. .directve handling needs the link.exe option parser.
