The new name clarifies the function's relation to getValueState. That is,
unlike getValueState, the state of a given value will not be initialized if
it's not already in the map.

This patch adds a post-linking pass which replaces the function pointer of enqueued
block kernel with a global variable (runtime handle) and adds
runtime-handle attribute to the enqueued block kernel.
In LLVM CodeGen the runtime-handle metadata will be translated to
RuntimeHandle metadata in code object. Runtime allocates a global buffer
for each kernel with RuntimeHandel metadata and saves the kernel address
required for the AQL packet into the buffer. __enqueue_kernel function
in device library knows that the invoke function pointer in the block
literal is actually runtime handle and loads the kernel address from it
and puts it into AQL packet for dispatching.
This cannot be done in FE since FE cannot create a unique global variable
with external linkage across LLVM modules. The global variable with internal
linkage does not work since optimization passes will try to replace loads
of the global variable with its initialization value.

Summary:
D36624 added some python3 compatibility. But that fix has a problem..
With python2 (which is specified by `#!/usr/bin/env python2.7`), if the env variables do not specify the UTF8,
and the source file is UTF8 (contains non-ASCII symbols), then the `.decode('utf-8')` causes the following exception:
```

UnicodeEncodeError: 'ascii' codec can't encode character u'\xf4' in position 47: ordinal not in range(128)
```
This is similar to https://bugs.llvm.org/show_bug.cgi?id=33548, which was fixed by https://reviews.llvm.org/D37661
Unlike that fix, here, *removing* `.decode('utf-8')` actually fixes it.
Since i assume that the original fix is needed, i simply made
that fix conditional, since for python2 it actually breaks things.

We just don't need one with the current setup.
We only error on undefined references that are used by some
relocation.
If we managed to relax all uses of __tls_get_addr, no relocation uses
it and we don't produce an error.
This is less code and fixes the case were we fail to relax. Before we
would produce a broken output, but now we produce an error.

Summary:
The pass to fix function bitcasts generates thunks for functions that
are called directly with a mismatching signature. It was also generating
thunks in cases where the function was address-taken, causing aliasing
problems in otherwise valid cases.
This patch tightens the restrictions for when the pass runs.

Summary:
The fact that `sanitizer_allocator_checks.h` is including `sanitizer_errno.h`
creates complications for future changes, where it would conflict with `errno.h`
definitions on Android and Fuchsia (macro redefinition).
By moving the portion that sets errno in the checks to a separate compilation
unit, we avoid the inclusion of the header there, which solves the issue.
Not that it is not vital to have that function in a header as it is called as a
result of an unlikely event, and doesn't need to be inlined.

Previously, the parsing of the 'subu $reg, ($reg,) imm' relied on a parser
which also rendered the operand to the instruction. In some cases the
general parser could construct an MCExpr which was not a MCConstantExpr
which MipsAsmParser was expecting.
Address this by altering the special handling to cope with unexpected inputs
and fine-tune the handling of cases where an register name that is not
available in the current ABI is regarded as not a match for the custom parser
but also not as an outright error.
Also enforces the binutils restriction that only constants are accepted.
This partially resolves PR34391.

Summary:
See https://llvm.org/PR33743 for more details
It seems that for non-power of 2 vector sizes, the algorithm can produce
non-matching sizes for input and result causing an assert.
This usually isn't a problem as the isAnyExtend check will weed these out, but
in some cases (most often with lots of undefined values for the mask indices) it
can pass this check for non power of 2 vectors.
Adding in an extra check that ensures that bit size will match for the result
and input (as required)
