The upper 32 bits are truncated before converting, which still produces
correct results since they never meaningfully contribute to the result.

The previous code produced incorrect results for inputs outside the
range [INT16_MIN, INT16_MAX].
A problematic case is e.g. i2f16 32768, which previously would be
converted to -32768.0 instead of returning the exactly representable
floating point result.

This function has evolved to be a generic helper function used throughout
the file, so having those assumptions written down explicitly and document
unsupported edge cases should help prevent incorrect use.

A Hitman 2 shader does: read64(local_invocation_index() * 4 - 4). This was
likely emitting a ds_read2_b32 on GFX6. For local_invocation_index()=0,
because the first dword was out-of-bounds, the second was likely also
considered out-of-bounds (even though it's not, at offset 0).

This reverts commit 1a0b0e8460.
The bounds checking behaviour of ds_read_b64, ds_read_b96 and ds_read_b128
make this feature very difficult to use safely.
This fixes a blocking artifact in Hitman 2. Previously, it contained:
ds_read_b64(local_invocation_index() * 4 - 4)
For local_invocation_index()=0, the second dword would be considered
out-of-bounds, even though it's at offset 0.

This becomes possible as long as we do
val = s_and_b32/64 exec, val
before any subgroup operations.
This precautional instruction can be removed by the
optimizer if 'val' was computed by a VOPC instruction
using the same exec mask.

We were incorrectly shifting the input VGPRs for the instance ID
for chips affected by the LS VGPR init bug (ie. Vega10 and Raven).
When there is no HS threads, the hardware loads the LS VGPR
starting from VGPR 0, so they should be shifted by two.
This fixes some sort of vertex explosion with Squad, Visage, Barn
Finders and probably more titles that use tessellation. Note that
only Vega10 and Raven were affected by this bug.
