Add getenv() wrapper that works on multibyte environment variable.
On Windows, character encoding of multibyte environment variable varies
depending on settings. The only reliable way to handle it I think is to use
GetEnvironmentVariableW().
GetEnvironmentVariableW() works on wchar_t string, which is on Windows UTF16
string. That's not ideal because we use UTF-8 as the internal encoding in LLVM.
This patch defines a wrapper function which takes and returns UTF-8 string for
GetEnvironmentVariableW().
The wrapper function does not do any conversion and just forwards the argument
to getenv() on Unix.

Debug Info: create scope children DIEs when the scope DIE is not null.
We try to create the scope children DIEs after we create the scope DIE. But
to avoid emitting empty lexical block DIE, we first check whether a scope
DIE is going to be null, then create the scope children if it is not null.
From the number of children, we decide whether to actually create the scope DIE.
This patch also removes an early exit which checks for a special condition.
It also removes deletion of un-used children DIEs that are generated
because we used to generate children DIEs before the scope DIE.
Deletion of un-used children DIEs may cause problem because we sometimes keep
created DIEs in a member variable of a CU.

[SystemZ] Add TM and TMY
The main complication here is that TM and TMY (the memory forms) set
CC differently from the register forms. When the tested bits contain
some 0s and some 1s, the register forms set CC to 1 or 2 based on the
value the uppermost bit. The memory forms instead set CC to 1
regardless of the uppermost bit.
Until now, I've tried to make it so that a branch never tests for an
impossible CC value. E.g. NR only sets CC to 0 or 1, so branches on the
result will only test for 0 or 1. Originally I'd tried to do the same
thing for TM and TMY by using custom matching code in ISelDAGToDAG.
That ended up being very ugly though, and would have meant duplicating
some of the chain checks that the common isel code does.
I've therefore gone for the simpler alternative of adding an extra
operand to the TM DAG opcode to say whether a memory form would be OK.
This means that the inverse of a "TM;JE" is "TM;JNE" rather than the
more precise "TM;JNLE", just like the inverse of "TMLL;JE" is "TMLL;JNE".
I suppose that's arguably less confusing though...

[python bindings] Added code to get the length of a memory buffer. Tests are included.
This is a part of a series of patches that have been sitting fallow on a
personal branch that I have been messing with for a bit.
The patches start to flesh out the python llvm-c wrapper to the point where you can:
1. Load Modules from Bitcode/Dump/Print them.
2. Iterate over Functions from those modules/get their names/dump them.
3. Iterate over the BasicBlocks from said function/get the BB's name/dump it.
4. Iterate over the Instructions in said BasicBlocks/get the instructions
name/dump the instruction.
My main interest in developing this was to be able to gather statistics about
LLVM IR using python scripts to speed up statistical profiling of different IR
level transformations (hence the focus on printing/dumping/getting names).
This is a gift from me to the LLVM community = ).
I am going to be committing the patches slowly over the next bit as I have time
to prepare the patches.
The overall organization follows the c-api like the bindings that are already
implemented.

Therefore, these instructions are “merged” by CSE at MI IR level.

Debug Info: Rename DITypeRef to DIScopeRef.
A reference to a scope is more general than a reference to a type since
DIType is a subclass of DIScope.
A reference to a type can be either an identifier for the type or
the DIType itself, while a reference to a scope can be either an
identifier for the type (when the scope is indeed a type) or the
DIScope itself. A reference to a type and a reference to a scope
will be resolved in the same way. The only difference is in the
verifier when a field is a reference to a type (i.e. the containing
type field of a DICompositeType) or a field is a reference to a scope
(i.e. the context field of a DIType).
This is to get ready for switching DIType::getContext to return

empty and the MDNode is DIType for TypeRef and DIScope for ScopeRef.
