We were previously setting an ignored bit in the kernel headers. The
current behavior is to add the large amount on top of the statically
known size of a single stack frame. I'm not sure if we should just use
the large size as the entire reported size instead.
By default clang emits complete contructors as alias of base constructors if they are the same.
The backend is supposed to emit symbols for the alias, otherwise it causes undefined symbols.
@yaxunl observed that this issue is related to the llvm options `-amdgpu-early-inline-all=true`
and `-amdgpu-function-calls=false`. This issue is resolved by only inlining global values
with internal linkage. The `getCalleeFunction()` in AMDGPUResourceUsageAnalysis also had
to be extended to support aliases to functions. inline-calls.ll was corrected appropriately.

For PS shaders we can use the input SPI_PS_INPUT_ENA and SPI_PS_INPUT_ADDR
registers
Calculate the number of VGPR registers used as input VGPRs based on these
registers rather than the arguments passed in (this conservatively always
allocates the maximum).

First, collect the register usage in each function, then apply the
maximum register usage of all functions to functions with indirect
calls.
This is more accurate than guessing the maximum register usage without
looking at the actual usage.
As before, assume that indirect calls will hit a function in the
current module.
