ECX new size of block, in bytes (must not be 0)
EDX flags: bit 0: 1=create committed pages
0=create uncommitted pages
bit 1: 1=descriptors require update (see Notes)
0=do not update descriptors
2-31: (reserved; should be 0)
EBX new linear base address of allocated block
ESI new handle used to resize and free this block
Info: Changes the size of a linear memory block allocated via
Notes: If bit 1 of EDX is set, then you must identify the descriptors
which need to be updated as follows: ES:EBX is the address of a
series of 2-byte selectors whose descriptors need updating and
EDI is the size of the array, in words.
