We were not properly accounting for the live register type of
global registers in GHC.CmmToLlvm.CodeGen.funPrologue. This meant that
we could allocated a register at type <4 x i32> but try to write to it
at type <8 x i16>, which LLVM doesn't much like.
This patch fixes that by inserting intermerdiate casts when necessary.
Fixes #25730

BCOs can be nested, resulting in nested BCO stack frames where the inner most
stack frame can refer to variables stored on earlier stack frames via the
PUSH_L instruction.
|---------|
| BCO_1 | -<-┐
|---------|
......... |
|---------| | PUSH_L <n>
| BCO_N | ->-┘
|---------|
Here BCO_N is syntactically nested within the code for BCO_1 and will result
in code that references the prior stack frame of BCO_1 for some of it's local
variables. If a stack overflow happens between the creation of the stack frame
for BCO_1 and BCO_N the RTS might move BCO_N to a new stack chunk while leaving
BCO_1 in place, invalidating a simple offset based reference to the outer stack
frames.
Therefore `ReadSpW` first performs a bounds check to ensure that accesses onto
the stack will succeed. If the target address would not be a valid location for
the current stack chunk then `slow_spw` function is called, which dereferences
the underflow frame to adjust the offset before performing the lookup.
┌->--x | CHK_1 |
| CHK_2 | | | |---------|
|---------| | └-> | BCO_1 |
| UD_FLOW | -- x |---------|

|---------| | PUSH_L <n>
| BCO_ N | ->-┘
