Benjamin Kramer 9a3bd23668 Prefix external symbols in llvm-c-test. 
This makes it less likely to clash with other stuff that might be linked
in by change, e.g. ncurses exposes an external function called simply
"echo", so linking ncurses statically into the binary explodes in funny
ways.

Amaury Sechet e8ea7d8b1d Improve testing for the C API 
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.

Rafael Espindola 2339ffed97 Deprecate a few C APIs. 
This deprecates:
* LLVMParseBitcode
* LLVMParseBitcodeInContext
* LLVMGetBitcodeModuleInContext
* LLVMGetBitcodeModule

They are replaced with the functions with a 2 suffix which do not record
a diagnostic.

Bjorn Steinbrink a09ac0085d Fix LLVMSetMetadata and LLVMAddNamedMetadataOperand for single value MDNodes 
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.

Anders Waldenborg b932c66955 Add llvm-c-test tool for testing llvm-c 
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
