x86-64: fix a problem exposed by negative offsets in vector tables static relative offsets (eg .long l1-l2) are restricted to 32 bits on x86-64 due to lack of support in the linker. The codegen, NCG and runtime work around this, using 32-bit offsets instead of 64. However, we were missing a workaround for vector tables, and it happened to work by accident because the offsets were always positive and resolved by the assembler. The bug was exposed by using the NCG to compile the RTS, where the offsets became negative, again by accident.

Replace inline C functions with C-- macros in .cmm code So that we can build the RTS with the NCG.

mpz_foo() functions are really called __gmpz_foo() in GMP gmp.h #defines mpz_foo to __gmpz_foo, so the real ABI is __gmpz_foo, so that is what we must invoke in order to be portable here. Similarly for mpn --> __gmpn.

fix some problems with the fixup block code We weren't handling InBoth properly. InBoth needs to be expanded to appropriate InReg/InMem locations *before* building the interference graph, otherwise an InBoth will not be seen to conflict with other InReg/InMem locations.

Use -fno-strict-aliasing for *all* C files in the runtime as a precautionary measure. It is definitely required for GC.c, but it may well become necessary for other files in the future due to our (mis-)use of the C "type system".

Be lazier in user config creation, and don't fail on missing configs.
