c8dbe1e5d6 Warn about unsupported codegen with the diags machinery, giving us:
t.c:3322:5: warning: cannot codegen this yet
    __asm__ ("bswap   %0" : "+r" (_data));
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

instead of:

Unimplemented stmt!

a96fe8d5c5 Add support for __builtin_expect which is needed for assert,
among other things.

Also change a codegen warning to dump to stderr so it doesn't
mess with -emit-llvm output

aefc8fd415 Support initalisers for more than just int-typed static variables.
We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

7d303b2a20 Better match llvm-gcc's behavior for CodeGen naming of anonymous structs and unions.

b0e6094a22 When generating the CodeGen type name of a struct, union, enum use the typedef
name if a tag type name is not available for the type. This matches how llvm-gcc 
chooses CodeGen type names.

This means that "typedef struct {...} foo" now results in a CodeGen name of 
"struct.foo" rather than "struct."

we didn't correctly promote the condition to the right
