Also update the OperationData constructor to use a Instruction&

Add support for .radix directive, and radix specifiers [yY] (binary), [oOqQ] (octal), and [tT] (decimal).
Also, when lexing MASM integers, require radix specifier; MASM requires that all literals without a radix specifier be treated as in the default radix. (e.g., 0100 = 100)

D87921 was reverted in commit b89059a313
as it was causing an unknown llvm PPC bot failure. Reapplying the patch
after confirming that this is not responsible. Build bot failure:

The wrong placement of add pass with optimizations led to
-funique-internal-linkage-names being disabled.
Fixed the placement of the MPM.addpass for UniqueInternalLinkageNames to make it

D87691 reordered some checks, which turned out to be unsafe. More
specifically, when examining a store instruction, the check against
getOrCreateResult should be done before attempting to call
isSameMemGeneration. Otherwise a crash in MSSA walker can occur.
This patch restores the order of these calls to what it was originally.
Implements IS_ABSOLUTE_PATH from GNU tools.
C++17 is_absolute behavior is different the from the behavior defined by GNU
tools.
According to cppreference.com, C++17 states: "An absolute path is a path
that unambiguously identifies the location of a file without reference
to an additional starting location."
In other words, the rules are:
1. POSIX style paths with nonempty root directory are absolute.
2. Windows style paths with nonempty root name and root directory are
absolute.
3. No other paths are absolute.
GNU rules are:
1. Paths starting with a path separator are absolute.
2. Windows style paths are also absolute if they start with a character
followed by ':'.
3. No other paths are absolute.
On Windows style the path "C:\Users\Default" has "C:" as root name and "\"
as root directory.
Hence "C:" on Windows is absolute under GNU rules and not absolute under
C++17 because it has no root directory. Likewise "/" and "\" on Windows are
absolute under GNU and are not absolute under C++17 due to empty root name.

MBFIWrapper keeps track of block frequencies of newly created blocks and
modified blocks, modified block frequencies should also impact block profile
count. This class doesn't provide interface getBlockProfileCount, users can only
use the underlying MBFI to query profile count, the underlying MBFI doesn't know
the modifications made in MBFIWrapper, so it either provides stale profile count
for modified block or simply crashes on new blocks.
So this patch add function getBlockProfileCount to class MBFIWrapper to handle
new blocks or modified blocks.

Currently, when marshaling a dynamic AST matchers, we check for the type
and value validity of matcher arguments at the same time for some matchers.
For instance, when marshaling hasAttr("foo"), the argument is first type
checked to ensure it's a string and then checked to see if that string can
locate an attribute with that name. Similar happens for other enumeration
conversions like cast kinds or unary operator kinds. If the type is
correct but the value cannot be looked up, we make a best-effort attempt
to find a nearby name that the user might have meant, but if one cannot
be found, we throw our hands up and claim the types don't match.
This has an unfortunate behavior that when the user enters something of
the correct type but a best guess cannot be located, you get confusing
error messages like:
Incorrect type for arg 1. (Expected = string) != (Actual = String).
This patch splits the argument check into two parts: if the types don't
match, give a type diagnostic. If the type matches but the value cannot
be converted, give a best guess diagnostic or a value could not be
located diagnostic. This addresses PR47057.

Blocks in a region and operations in a block are organized in a linked list.
The C API only provides functions to append or to insert elements at the
specified numeric position in the list. The latter is expensive since it
requires to traverse the list. Add insert before/after functionality with low
cost that relies on the iplist elements being convertible to iterators.

* The API is a bit more verbose than I feel like it needs to be. In a follow-up I'd like to abbreviate some things and look in to creating aliases for common accessors.
* There is a lingering lifetime hazard between the module and newly added operations. We have the facilities now to solve for this but I will do that in a follow-up.
* We may need to craft a more limited API for safely referencing successors when creating operations. We need more facilities to really prove that out and should defer for now.

This is an attempt to separate out the logic for computation of derived
