[CMake] Cleaning up some CMake warnings
In Bootstrap builds Clang logs some warnings. These are caused because Clang passes CLANG_STAGE and BOOTSTRAP_DEFAULT_PASSTHROUGH into the next stage's configuration.
BOOTSTRAP_DEFAULT_PASSTHROUGH shouldn't be passed, so it is renamed to _BOOTSTRAP_DEFAULT_PASSTHROUGH, to prevent passthrough.
CLANG_STAGE should be passed, so I've changed the code to log it if it is set outside the if(CLANG_ENABLE_BOOTSTRAP) block. This makes the variable always used, so the warning goes away.

[PGO] Fix profile mismatch in COMDAT function with pre-inliner
Pre-instrumentation inline (pre-inliner) greatly improves the IR
instrumentation code performance, among other benefits. One issue of the
pre-inliner is it can introduce CFG-mismatch for COMDAT functions. This
is due to the fact that the same COMDAT function may have different early
inline decisions across different modules -- that means different copies
of COMDAT functions will have different CFG checksum.
In this patch, we propose a partially renaming the COMDAT group and its
member function/variable so we have different profile counter for each
version. We will post-fix the COMDAT function and the group name with its
FunctionHash.

StringSwitch cannot be copied (take 2).
This prevents StringSwitch from being used with 'auto', which is
important because the inferred type is StringSwitch rather than the
result type. This is a problem because StringSwitch stores addresses
of temporary values rather than copying or moving the value into its
own storage.
This is a compromise that still allows wrapping StringSwitch in other
temporary structures, which (unlike StringSwitch) may be non-trivial
to set up and therefore want to at least be movable. (For an example,
see QueryParser.cpp in clang-tools-extra.)

BLIS implements gemm as three nested loops around a macro-kernel, plus

is a loop around a rank-1 (i.e., outer product) update. In this change

This is a breaking change. The SFINAE required is instantiated the second
the class is instantiated, and this can cause hard SFINAE errors
when applied to references to incomplete types. Ex.
struct IncompleteType;
extern IncompleteType it;
std::tuple<IncompleteType&> t(it); // SFINAE will blow up.

Don't SFINAE pair's copy assignment operator in C++03 mode.
In C++03 mode evaluating the SFINAE can cause a hard error due to
access control violations. This is a problem because the SFINAE
is evaluated as soon as the class is instantiated, and not later.

Make readExpr return an Expr object instead of a vector of tokens.
Previously, we handled an expression as a vector of tokens. In other
words, an expression was a vector of uncooked raw StringRefs.
When we need a value of an expression, we used ExprParser to run
the expression.
The separation was needed essentially because parse time is too
early to evaluate an expression. In order to evaluate an expression,
we need to finalize section sizes. Because linker script parsing
is done at very early stage of the linking process, we can't
evaluate expressions while parsing.
The above mechanism worked fairly well, but there were a few
drawbacks.
One thing is that we sometimes have to parse the same expression
more than once in order to find the end of the expression.
In some contexts, linker script expressions have no clear end marker.
So, we needed to recognize balanced expressions and ternary operators.
The other is poor error reporting. Since expressions are parsed
basically twice, and some information that is available at the first
stage is lost in the second stage, it was hard to print out
apprpriate error messages.
This patch fixes the issues with a new approach.
Now the expression parsing is integrated into ScriptParser.
ExprParser class is removed. Expressions are represented as lambdas
instead of vectors of tokens. Lambdas captures information they
need to run themselves when they are created.
In this way, ends of expressions are naturally detected, and
errors are handled in the usual way. This patch also reduces
the amount of code.
