llvm-symbolizer: make mangled name heuristic apply to all symbols

Tweak the MCExternalSymbolizer to print references to C string literals
with raw_ostream's write_escaped() method.

For example darwin's otool(1) program that uses the llvm
disassembler now produces disassembly like this:

leaq	0x7b(%rip), %rdi ## literal pool for: "%f\ntoto\n"

and not print the new lines which messes up the output.

LTO: document LTO_API_VERSION for each API

Adding a doxygen comment for each bit of API to indicate at which
LTO_API_VERSION each was available, manually gleaned from successive
git-blames.  A few notes:

- LTO_API_VERSION was set to 3 at its introduction.
- I've indicated all the API introduced before LTO_API_VERSION was
  around as available "prior to LTO_API_VERSION=3".
- A number of API changes neglected to bump LTO_API_VERSION.  These I've
  indicated as available at the *next* bump of LTO_API_VERSION.

[opt][PassInfo] Allow opt to run passes that need target machine.

When registering a pass, a pass can now specify a second construct that takes as
argument a pointer to TargetMachine.
The PassInfo class has been updated to reflect that possibility.
If such a constructor exists opt will use it instead of the default constructor
when instantiating the pass.

Since such IR passes are supposed to be rare, no specific support has been
added to this commit to allow an easy registration of such a pass.
In other words, for such pass, the initialization function has to be
hand-written (see CodeGenPrepare for instance).

Now, codegenprepare can be tested using opt:
opt -codegenprepare -mtriple=mytriple input.ll

Change inalloca rules to make it only apply to the last parameter

This makes things a lot easier, because we can now talk about the
"argument allocation", which allocates all the memory for the call in
one shot.

The only functional change is to the verifier for a feature that hasn't
shipped yet.
