Fix incorrect target triple in fp16-promote.ll

[pirama]

Summary

Hyphens were missing from the triple, causing it to be parsed
incorrectly. This patch updates the triple and makes necessary
changes to the expected output.

Patch is from Vinicius Tinti.

Hi,

This is weird, and I'd like to know more why the extra dash makes that big a difference...

cheers,

It is because the "environment" is not parsed in the original case.
Thus Subtarget->isTargetAnything won't work because the "environment" is set to Unknown.

This is the environment parser:

Frontends emit LLVM IR with --- (three dashes) to avoid ambiguous interpretation. Example:

; ModuleID = 'main.c'
target datalayout = "e-m:e-p:32:32-i64:64-v128:64:128-a:0:32-n32-S64"
target triple = "armv7---eabihf"

Abiguous triples are only accepted in -target in Clang for compatibility reasons.

Indeed! LGTM. Thanks!
