Summary:
This basically add an echo test case in C. The support is limited right now, but full support would just be too much to review at once.
The echo test case simply get a module as input and try to output the same exact module. This allow to check the both reading and writing API are working as expected.
I want to improve this test over time to support more and more of the API, in order to improve coverage (coverage is quite poor right now).
Test Plan: Run the test.

This deprecates:
* LLVMParseBitcode
* LLVMParseBitcodeInContext
* LLVMGetBitcodeModuleInContext
* LLVMGetBitcodeModule
They are replaced with the functions with a 2 suffix which do not record
a diagnostic.

Summary:
This patch introduces two new function attributes
InaccessibleMemOnly: This attribute indicates that the function may only access memory that is not accessible by the program/IR being compiled. This is a weaker form of ReadNone.
inaccessibleMemOrArgMemOnly: This attribute indicates that the function may only access memory that is either not accessible by the program/IR being compiled, or is pointed to by its pointer arguments. This is a weaker form of ArgMemOnly
Test cases have been updated. This revision uses this (d001932f3a) as reference.

This attribute allows the compiler to assume that the function never recurses into itself, either directly or indirectly (transitively). This can be used among other things to demote global variables to locals.

Dissasembly tests depends on target. The problem is that it disable
all tests if all targets are not compiled. This moves things around in
order to get target specific code in a target specific folder.
Patch by Amaury Sechet. Thanks!

Summary:
MetadataAsValue uses a canonical format that strips the MDNode if it
contains only a single constant value. This triggers an assertion when
trying to cast the value to a MDNode.

Summary:
Until r216870 LLVMCreateObjectFile returned nullptr in case of an error,
so callers could check if the call was successful. Now, it always
returns an OwningBinary wrapped as an LLVMObjectFileRef, so callers
can't check if the call was successul.
This results in a segfault running e.g.
llvm-c-test --object-list-sections < /dev/null
So the old behaviour should be restored.

This provides rudimentary testing of the llvm-c api.
The following commands are implemented:
* --module-dump
Read bytecode from stdin - print ir
* --module-list-functions
Read bytecode from stdin - list summary of functions
* --module-list-globals
Read bytecode from stdin - list summary of globals
* --targets-list
List available targets
* --object-list-sections
Read object file from stdin - list sections
* --object-list-symbols
Read object file from stdin - list symbols (like nm)
* --disassemble
Read lines of triple, hex ascii machine code from stdin - print disassembly
* --calc
Read lines of name, rpn from stdin - print generated module ir
