Summary:
Some compilers where failing with this file because the number of symbols was above 2**15.
- Replace std::list<> and std::vector<> with plain arrays.
- Change VariadicMatcherCreateCallback to be a function template, and a
  single class that wraps the instantiations.
- Remove some more unnecessary template arguments and function calls.

Instead of a custom implementation of replaceAllUsesWith, we just call
replaceAllUsesWith and recreate llvm.used and llvm.compiler-used.

This change is particularity interesting because it makes llvm see
through what clang is doing with static used functions in extern "C"
contexts. With this change, running clang -O2 in

extern "C" {
  __attribute__((used)) static void foo() {}
}

produces

@llvm.used = appending global [1 x i8*] [i8* bitcast (void ()* @foo to
i8*)], section "llvm.metadata"
define internal void @foo() #0 {
entry:
  ret void
}

Remove eFormatHalfFloat as it isn't needed. eFormatFloat should be used and the byte size will tell us how to display it.

It will be tested in the next commit which moves another user to identify_magic.

Original message:

Fix an out of bounds array access.

We were looking at Magic[5] without checking Length. Since this path would not
return unless Length >= 18 anyway, just move the >= 18 check up.

Summary:
"//Test" becomes "// Test". This change is aimed to improve code
readability and conformance to certain coding styles. If a comment starts with a
non-alphanumeric character, the space isn't added, e.g. "//-*-c++-*-" stays
unchanged.

This enables the compiler to see the enum and produce warnings about a switch
not being fully covered. Fix one of these warnings.

The effect of llvm.used is to introduce an invisible reference, so this seems
a reasonable restriction. It will be used to provide an easy ordering of
the entries in llvm.used.

The yaml reader is not specific to any file format. This patch moves
it to TargetInfo and makes validate a non virtual interface so that it
can be constructed from a single location.

The same method will be used to create a reader for llvm bitcode
files.

Negative zero is returned by the primary expression parser as INT32_MIN, so all that the method needs to do is to accept this value.
Behavior already present for Thumb2.

This patch adds support for FPINST/FPINST2 as operands to vmsr/vmrs. These are optional registers that may be supported some ARM implementations to aid with resolution of floating point exceptions. The manual pages for vmsr and vmrs do not detail their use. Encodings and other information can be found in ARM Architecture Reference Manual section F, chapter 6, paragraph 3.
