[compiler-rt] [builtins] Fix floattitf.c etc. compilation on Solaris/SPARC (PR #70058)

[Rainer Orth via llvm-commits]

https://github.com/rorth created https://github.com/llvm/llvm-project/pull/70058

69660ccf2ae402b02799efed072afd8ecf5a6eb0 broke the [Solaris/sparcv9 buildbot](https://lab.llvm.org/staging/#/builders/12/builds/264): `compiler-rt/lib/builtins/int_to_fp.h` unconditionally uses `*int128_t` which don't exist on 32-bit SPARC.

As suggested in https://github.com/llvm/llvm-project/pull/67540, this patch fixes this by moving the `CRT_HAS_TF_MODE` guard up which does the necessary checks.

Tested on `sparcv9-sun-solaris2.11`.

Subject: [PATCH] [builtins] Fix floattitf.c etc. compilation on Solaris/SPARC

69660ccf2ae402b02799efed072afd8ecf5a6eb0 broke the Solaris/sparcv9 buildbot
https://lab.llvm.org/staging/#/builders/12/builds/264:
`compiler-rt/lib/builtins/int_to_fp.h` unconditionally uses `*int128_t`
which don't exist on 32-bit SPARC.

As suggested in https://github.com/llvm/llvm-project/pull/67540, this patch
fixes this by moving the `CRT_HAS_TF_MODE` guard up which does the
necessary checks.

Tested on `sparcv9-sun-solaris2.11`.
